13. Optimizing and speedtest 14. My old real Z80 System   0. GLOSSARY: =========== bios Is the part of the bios which is witten in Z80 assembler. It acts as an interface to the yaze-bios. Here are central definitions (drive tables, yaze control table (YCT), ...) which are essential for the whole system. yaze-bios Is the part of the bios which is written in C.   1. FEATURES: ============ I took the idea of the page tables from Michael Hardt and built a simulated MMU. The default definitions of the MMU are 16 tables with 16 page pointers (page size 4 KB) per table. You can run on yaze-ag-2.40.5 CP/M 2.2 or superdos (file: yaze.boot) with or without the MMU and 64 KB like the older version yaze-1.10 or you can run CP/M 3.1 or ZPM3 from Simeon Cran (file: yaze-cpm3.boot) always with the MMU and RAM up to 1MB. You can start CP/M 3.1 by simply executing the file CPM3.COM under CP/M 2.2 or CP/M 3.1 (for example with a new bios version). The new CP/M 3.1 loader BOOTSYS (see above) relocates and starts the appended CPM3.SYS and if CP/M 3.1 is running firstly all will be transferred from bank 1 (TPA) to bank 0 (SYS bank) with an interbank move (XMOVE/MOVE). The CP/M 3.1 bios (acts as an interface to the yaze-bios) and the yaze-bios (ybios.c) uses the MMU intensive like a real Z80 CP/M 3.1 System (destination/source bank for read/write disk and interbank moves, multi-i/o is also implemented). Ten new options are described in the Makefile. Following features are implemented: simz80.c I made some optimizations and made the necessary changes to embed the MMU. (See above the file simz80.c, the option -DMMU and above "Optimizing".) MMU with 16 tables to 16 page pointers (page size 4 KB). A bank switch over the bios is simple done with a pointer and very fast (see *mmu in the new module mem_mmu.[hc]). I made a lot of changes in all modules to embed the MMU in the whole system. You can run CP/M 3.1 (bootfile: yaze-cpm3.boot) or CP/M 2.2 (yaze.boot) on yaze-ag-2.40.5. You can start CP/M 3.1 by simply executing CPM3.COM (bootsys.com+cpm3.sys). (yaze-cpm3.boot is identically with cpm3.com) BOOTSYS Bootsys is a new CPM3.SYS loader. It was necessary because the CPM3.SYS grows over 32K and the CPMLDR or ZPM3LDR does not load this big file. (See above "Some words to BOOTSYS".) CP/M 3.1 All fundamental and essential functions are made for running CP/M 3.1 . The following features are not necessary but CP/M 3.1 supports it: DATE implemented XMOVE/MOVE implemented - this supports sector size > 128 Bytes (Default sector size is now 2048 bytes.) MULTIO multi-i/o is also implemented and runs very well. Mounting Directories special feature to import directories into the emulator by connecting them to CP/M drives. By that way you can easily import files into the emulator. The new feature in version 2.12 is that the update time stamps are imported into the simulated CP/M directory. Look to chapter 7. Mounting directories with Time Stamps in this document. Import/Export utilities Since version 2.30 you can import files with the utility R.COM without exiting the emulator. Also with W.COM you can export files to the host system without exiting the emulator. Look to chapter 8. Import and Export utilities serial lines since version 2.20 you can use the serial lines of your computer. Look to chapter 9. Serial Lines. Following features are NOT implemented char devices not yet implemented - Yaze uses the I/O-byte like CP/M 2.2 . I will do this in the future.   2. DEVELOPMENT: ================ I developed under Solaris 8 (sparcv9) and Linux (kernel 2.4.x/2.6.x) and used gcc version 3.x.x also under Solaris. I tested yaze-ag-2.20 on FreeBSD and DEC-Unix (alpha processor) - it works also there. I have not yet tested yaze-ag-2.20 on FreeBSD or DEC-Unix. You can also compile YAZE-AG with the SPARC-C-Compiler of SUN/Oracle. I had a lot of fun in developing the bios and the yaze-bios for CP/M 3.1, but sometimes I was stunned - but I found the errors :-) . (see above section "My old real Z80 system") The known bug of version 2.01 is solved. I add the more feature to import the modification time of the unix files as update time under CP/M. Look Chapter 7 "Mounting directories with Time Stamps" in this document. Since this pre release 2.00 you can use the "cdm" utility (CP/M Disk Manager) also under Linux. I have finished with this development cycle. Look to Chapter "FIXED BUGS" and chapter "Serial Lines". Today 3. January 2018 there are no known bugs in version 2.40.5. 3. January 2018 Andreas Gerlich (University of Ulm, Germany) only text emails please: address removed !!!   3. Fixed BUGS: ============== Timothy Wagner and Carl Mascott reports a complex bug in yaze-ag-2.00. I found this error also when I work with the emulator (and with drives which are connected to a unix directory) and so I test also the old version yaze-1.10. This bug is also in yaze-1.10! I take the code to access unix directories from yaze-1.10 (see old version on the web page). Bug report 1: When you use the feature to connect a directory to a CP/M drive (A: - P:) this works if you use it to copy files from a directory to a disk-file under yaze-ag. But if you use it to import files from a Directory to compile sources and run programms while you edit source files with vi under Unix/Linux the emulator crashes after some time when you often access files on the drive which are connected to a directory. THIS BUG IS FIXED IN VERSION 2.01 !!! Bug report 2: When you have two unix files like "Source.z80" and "source.z80" this are two different files under unix. CP/M does not handle upper and lower case of file names. All file names are holded upper case in the CP/M directories. When a unix directory was mounted and there was files like the two z80 files yaze-1.10 and yaze-ag-2.00 creates two CP/M directory entries with the name "SOURCE.Z80". This was a problem and the emulator crashes. THIS BUG IS FIXED IN VERSION 2.01 !!! Bug report 3: When you use also the feature to mount unix directories to a CP/M drive, the problem is that if you edit a file with vi or nedit under unix the emulator don't know about this changes or new files until you make a "remount". THIS REREAD BUG IS FIXED IN VERSION 2.10 !!! See chapter 7 "Mounting directories with Time Stamps". Bug 4 which I found: When you use also the feature to mount unix directories to a CP/M drive, the problem was that when the filesize of a file was multiple of exactly 16K (16k,32K...) the last 16k can not read. If a file was exactly 16k you only get the first 128 Byte when you make a "type" on a source file for example. It was a chance to find this bug, The bug was in the simulated directory for CP/M when you connect a Unix directory to a CP/M drive. THIS SIMULATION DIRECTORY BUG IS FIXED IN VERSION 2.20.1 !!! Its recommended to update the executable to this version 2.20.1 !!! In yaze-ag-2.40.5 there are no known bugs! I mean there are no further errors but if you find one feel free and send an email to me. If you miss a feature feel free and send an email to me, too. 3. January 2018 Andreas Gerlich (University of Ulm, Germany) only text emails please: address removed !!!   =========================================== 4. Some words to BOOTSYS (CP/M 3.1 loader): =========================================== The BIOS3 under Z80 (acts as an interface to the yaze-bios (bios.c) with the files BIOSKRNL.Z80, YDRVTBL.Z80, MMU.Z80, YCT.Z80 and SCB.Z80, linked with BNKBDOS3.SPR and RESBDOS3.SPR to CPM3.SYS by GENCPM.COM (see drive P:)) supports all 16 drives from A: to P: . All tables for these drives (defined in YDRVTBL) are very big - CPM3.SYS is 44KB! All tables are defined to handle disks up to 64 MB. Greater disks will not work, but it is possible to create them in the monitor in yaze-ag (and cdm) and then you have to change the definitions in YDRVTBL.Z80/SYSDEF.LIB. When CPM3.SYS gets over 34KB, CPMLDR (ZPM3LDR cannot run with my loader bios ?!?!) cannot load this big file (I don't know why and I don't want to debug it). So I had to look for another way to load CPM3.SYS. I search for informations of the file structure of CPM3.SYS. So I developed BOOTSYS.Z80. It relocates the resident and banked part (if present) held in the joined CPM3.SYS and jumps into the bios to start CP/M 3.1. | BOOTSYS works very well. BOOTSYS.Z80 is written, so that BOOTSYS runs also | on a real CP/M System. If the cp/m vectors are present BOOTSYS prints the | messages over the bios (conout), if not, it uses the yaze-bios directly | over the HALT instruction. BOOTSYS should be run always under a real | Z80 CP/M 2.2 system to start CP/M 3.1 (I use Z80 instructions). If CP/M 3.1 is always running BOOTSYS try to move BOOTSYS+CPM3.SYS from bank 1 to bank 0 switch to bank 0 and relocates and start CP/M 3.1. Under YAZE-AG-2.30.2 BOOTSYS is in the position to start always CP/M 3.1 under CP/M 3.1! WHY? In YAZE-AG-2.30.2 the XMOVE and MOVE routines are definded outside the Z80 memory in C and the short routines to call the yaze-bios are in the resident part of the bios, so all works well under YAZE-AG-2.30.2. If in a real Z80 CP/M 3.1 system the XMOVE/MOVE routines are placed in the banked part of a bios (possible if a DMA make the interbank transfere) then it can be that this parts will be overwritten when bootsys+cpm3.sys are transfered from bank 1 to bank 0. In this case you can not make a new start of CP/M 3.1 under CP/M 3.1. You must run CPM3.COM from CP/M 2.2 (You generate CPM3.COM by "PIP CPM3.COM=BOOTSYS.COM,CPM3.SYS"). How BOOTSYS works and what conditions are necessary to run under CP/M 3.1 is described in README_BOOTSYS. BOOTSYS+CPM3.SYS is also in the file yaze-cpm3.boot which is loaded instead of yaze.boot if the C-compiler option -DBOOTSYS is defined in the Makefile. It is the same file like CPM3.COM on drive A: . I transfer it to Unix/Linux and name it yaze-cpm3.boot.   5. New option and new monitor commands ====================================== You can call yaze-ag with the option '-1'. This option force sector size 128 bytes. Normally sector size is 2048 bytes under CP/M 3.1. Under CP/M 2.2 yaze-ag uses always sector size 128 bytes. If you go with the sys.com utility into the monitor you can give the new command '128'. This forces sector size 128 byte, too. This option was necessary because some disk edited utilities (like DED.COM) does not work with sektor size 2048. The command 'setaccess on/off' switch on/off the access time for mounted directories connected to a CP/M drive. The update time is always on. Create time stamps are not supported by the host systems. I expand the mount command. If you give "mount -v" you will get very detail informations about the connected drives/directories if you have started CP/M 3.1.   6. CP/M disks ============= I describe here only the changes in the disk header of a <CPM_Disk> (.ydsk files). Look for details to chapter 6. "CP/M disks" in yaze.doc. The new disk header occupies the first 128 BYTES of the file and has the new format: 0 - 9 <CPM_Disk> 10 - 15 a null-terminated ascii comment (may be empty) new 16 version (0 = yaze-1.06/1.10, 1 = yaze-ag-2.xx) 17 - 31 a null-terminated ascii comment (may be empty) 32 - 33 sectors per track 34 block shift factor 35 block mask 36 extent mask 37 - 38 disk size max 39 - 40 directory max 41 al0 42 al1 43 - 44 check size (always zero) 45 - 46 track offset new 47 psh (used if version=1 and CP/M 3.1 is running) new 48 phm ( " " " " " " " " " ) 49 - 127 unused (zeros) If version is 0 the sektor size is set to 128 bytes (psh=0, phm=0) in the DPB of the corresponding drive. Psh and phm are only used under CP/M 3.1 if version is 1. You can alway transfere disk files between an old version of yaze (1.06/1.10) and yaze-ag-2.30.2. The new disks looks under yaze-1.10 like a disk with sektor size 128 bytes. The new fields are ignored. You can also use your old disk files of yaze-1.10/1.06 under yaze-ag-2.30.2. The field "version" is in disk files from yaze-1.10/1.06 always 0. The fields version, psh and phm are used only in yaze-ag-2.xx and if CP/M 3.1 is running. The default sektor size is 2048 bytes (psh=4, phm=15). I change also the default value of sektors per track to 128. (The old value was 26). You can set 128 byte sektors (psh=0, phm=0) for all disk with the flag "-1" or the new monitor command "128". This was necessary because some disk edited utlilities (like DED.COM) does not work with sektor size 2048 bytes.   7. Mounting directories with Time Stamps ======================================== This chapter describes the special feature to import directories into the emulator by connecting them to CP/M drives. That way you can easily import files into the emulator. (An another way to import files is to use the cdm utility (CP/M disk manager). Only with cdm you can also export files (see man page cdm.1 or cdm(1)). ) But you can also use the feature "Mounting Directories" to compile/assemble source files which you import over a drive which is connected to a directory. That way you can edit files with vi or an another editor under unix and compile it inside yaze-ag. You can use the make.com utility which is on A: (disk file: BOOT_UTILS) because the update time stamps are imported from the host system and are present in the simulated CP/M directory! (Look above the submit file examples in this chapter!) But you have to take notice of some things: 1. The mounted directory is always read only. 2. You have to syncronise the simulated directory inside yaze-ag / CP/M and the directory of the host which is connected to a CP/M drive. The second point means: If you change a file with an editor under Unix the CP/M inside yaze-ag don't knows about these changes --> you must sync the simulated directory under CP/M with the connected unix directory. At that moment CP/M knows about changed and new files in the unix directory. To sync (reread) the mounted directories you have four ways to do this: a) CTRL-C at the command prompt (CCP). b) to use the utility "resetdsk.com" (see A: disk file BOOT_UTILS). c) to use the monitor command "sys remount <drive>" d) to use the monitor command "sys mount <drive> <directory-path>" 'a' is for online use. 'b', 'c' and 'd' is for use in a submit file. To a) (CTRL-C): the left side is for CP/M the right side is the host on which yaze-ag inside yaze-ag runs (for example an unix host) (C: is connected to ./disksort/) I make in CP/M: A>C: C>3dir disksort.c NAME UPDATE ---------- ... ---------------- DISKSORT.C 14/04/2004 10:20 notice: the time is 10:20 then I make under unix: $ pwd .../disksort $ date Wed Apr 14 17:44:01 MEST 2004 $ touch disksort.c notice: with touch I set the time to 17:44:xx then I make in CP/M: C>3dir disksort.c NAME UPDATE ---------- ... ---------------- DISKSORT.C 14/04/2004 10:20 notice: the time is still 10:20 C> C> C>^C (<--- give CTRL-C !!!) C> (this makes a reread of ./disksort/) C> C> C>3dir disksort.c NAME UPDATE ---------- ... ---------------- DISKSORT.C 14/04/2004 17:44 ^^^^^ notice: | The time of disksort.c is now / Technical Background: When you give a CTRL-C at the Command prompt CP/M resets the whole disk system. At the next bios call of seldsk (select disk) CP/M say in a flag "first access to this drive". Any further calls of seldsk to the same drive have not set this flag. I use this flag to make a reread of the unix directory. If you want to show also the access time stamps of a mounted directory see the monitor command "setacces on/off" in the chapter 5 "New option and new monitor commands". (I can not set "access time stamps" in the LabelByte of the disk label because CP/M tries to update the access time when you access a file in the (unix) directory (directories are always read only). DIR.COM shows the access time but say it is the creation time. 3DIR.COM of the ZINC project (drive F:) say correctly access time.) When you force a reread of a mounted directory also the changed size of each file is updated. The following submit file examples are on drive D: which is connected to the disk file DISKSORT.dsk. It contains the DISKSORT project which is described under http://www.mathematik.uni-ulm.de/users/ag/cpm/index.html#disksort These disk file is formated with INITDIR.COM (see "HELP INITDIR") and in the label "DISKSORT" the update time stamps are set (see "HELP SET LABEL" and "HELP SET TIME-STAMPS"). The source files are in the (unix-)subdirectory ./disksort/ which is connected to the CP/M drive C: To b): To use the "resetdsk.com" utility is like CTRL-C. It resets the disk system over the BDOS call no 37 . You can use "resetdsk.com" in the following example: D.sub: ; resetdsk ; ; this resets the whole disk system (all disks). ; ; ; Now compile the source ; make -f disksort.mak $1 ; ; This makefile makes a time comparison between the source files ; on drive C: (connected to unix directory ./disksort, read-only) ; and the compiled rel-files on drive D: (connected to the disk file ; "DISKSORT.dsk", read-write). ; Drive D: (the target) must initialized with INIRDIR.COM ; (see "HELP INITDIR") and you must create a label and update time with ; "SET [NAME=<LABEL-NAME>,UPDATE=ON] (see "HELP SET"). ; NOTICE: The example D.Sub is on D: and you have to call this submit file from D: (Look to the rules in the make file disksort.mak). To c): To use the monitor command "sys remount <drive>" is the same as resetdsk.com. It's only an another way. DD.sub: ; sys remount c ; ; this resets drive C: (it must be connected to a directory). ; ; ; Now compile the source ; make -f disksort.mak $1 ; ; This makefile makes a time comparison between the source files ; on drive C: (connected to unix directory ./disksort, read-only) ; and the compiled rel-files on drive D: (connected to the disk file ; "DISKSORT.dsk", read-write). ; Drive D: (the target) must initialized with INIRDIR.COM ; (see "HELP INITDIR") and you must create a label and update time with ; "SET [NAME=<LABEL-NAME>,UPDATE=ON] (see "HELP SET"). ; NOTICE: The example DD.Sub is on D: and you have to call this submit file from D: To d): To use the monitor command "sys mount <drive> <directory-path>" is not the same as the last examples: DDD.sub: ; sys mount c ./disksort/ ; ; this (re)mounts the directory ./disksort to CP/M drive C: ; (this is like a remount) ; ; ; Now compile the source ; make -f disksort.mak $1 ; ; This makefile makes a time comparison between the source files ; on drive C: (connected to unix directory ./disksort, read-only) ; and the compiled rel-files on drive D: (connected to the disk file ; "DISKSORT.dsk", read-write). ; Drive D: (the target) must initialized with INIRDIR.COM ; (see "HELP INITDIR") and you must create a label and update time with ; "SET [NAME=<LABEL-NAME>,UPDATE=ON] (see "HELP SET"). ; NOTICE: DDD.Sub is on D: and you have to call this submit file from D: The difference between this submit file and the previous submit files is that you can have different submit files on different drives. Each submit file uses an another directory path for drive C: and so you can compile different projects on different disk files. "sys mount <drive> <directory-path>" (re)mounts a directory. The mount command (of the monitor) makes internally first an unmount of the <drive> and then reads the whole directory which is give as the second parameter <directory-path>. CP/M in Yaze-ag knows at this moment about new and changed files in the unix directory <directory-path>. 20.

Import and Export utilities R.COM and W.COM: =============================================== Since version 2.30 there exists two utilities for import and export files from and to the host system. With the R.COM utility you can import files from the host system into the emulator without exiting the emulator! When you call R.COM without a parameter it tells you how you use it: A>r READ V-2.23-1.00 (11-Sep-2009) YAZE-AG V2.30 Usage: READ [L] Binary copy from host environment. L = use lower case for name. Examples READ bdos.mac copy BDOS.MAC to BDOS.MAC READ bdos.mac L copy bdos.mac to BDOS.MAC READ *.mac copy all files ending with .MAC READ a:bdos.mac copy BDOS.MAC to A: READ a:*.com copy all .COM files to A: READ src/bdos.mac copy SRC/BDOS.MAC to BDOS.MAC READ src/a:bdos.mac copy SRC/BDOS.MAC to BDOS.MAC on A: READ src/*.mac copy all .MAC files from directory SRC READ src/*.MAC L copy all .mac files from directory src READ src/a:test.* copy all TEST.* files from directory SRC to A: A> With the W.COM utility you can export files to the host system from the emulator without exiting the emulator! When you call W.COM without a parameter it tells you how you use it: A>w WRITE V-1.17-1.00 (27-Aug-2009) YAZE-AG V2.30 Usage: WRITE [B|T] Copy to host environment. Default is text, B for binary, T for Text Examples WRITE BDOS.MAC copy BDOS.MAC as text file WRITE PIP.COM B copy PIP.COM as binary file WRITE PIP.COM copy PIP.COM as binary file [.COM .REL .DAT imply B] WRITE TEST.DAT T copy TEST.DAT as text file WRITE *.COM copy all files matching *.COM as binary files WRITE SRC/BDOS.MAC copy BDOS.MAC to directory "./SRC" as a text file WRITE COM/*.COM B copy *.COM to directory "./COM" as binary files WRITE SPL/*.SPL T copy *.SPL to directory "./SPL" as text files Files with the same name at the host environment will be overwritten without any query!!! A> The utilities are written in SPL (Simple Program Language) and compiled with the SPL environment which is on drive L: (spl.ydsk). The submit file Y.SUB compiles YWRITE.SPL and link it to A:W.COM. The submit file Z.SUB compiles YREAD.SPL and link it to A:R.COM. only text emails please: address removed !!! (email of the project)   9. Serial Lines: ================ With the "attach"-command in the monitor you can handle the serial lines: (You call the monitor with "sys.com" and no parameter.) For Solaris on SUN-Machines the device is /dev/ttya for the first serial port /dev/ttyb for the second serial port For Linux (PC) the device is /dev/ttyS0 for COM1 /dev/ttyS1 for COM2 ... For Cygwin the device is /dev/ttyS0 or /dev/com1 for COM1 /dev/ttyS1 or /dev/com2 for COM2 ... How the devices is called on MAC OS X I dont't know. You can write the attach command into the .yazerc file (edit it with vi in Unix/Linux or with the metapad.exe in Windows). Then you have always the serial line connected. The command you must write is: attach aux /dev/ttyS0 (for example) This connects the aux-device of CP/M 3 with the device in Unix/Linux/Windows. Then you have to make a Nullmodem cable to connect the two computers. (You must see in your technical documentation of your computer. I have cables which uses on the PC side the 9-pole connector and on the side of the Z280-Computer also a 9-pole connector, but with an another pin content) On the disk-file "Kermit_SZRZ.ydsk" are the programms kermit.com, sz.com and rz.com (ZModem). With them you can connect to the other computer and transfere data. Baud rate: You use the "DEVICE.COM" programm under CP/M 3 to set the baud rate. On my Z280 Computer (CPU280 by Reh Designe) I can set the baud rate in the Setup-routine of the boot loader. In Unix/Linux you use the "stty" programm.(see "man stty") Kermit (called ckermit) is available for Unix/Linux. With the kermit.com inside YAZE-AG when yaze_bin runs you can also communicate with a real CP/M computer. Under Windows you can use the Hyperterminal to initialize the COM-Port. I have an Icon with the Baud rate 19200 on my desktop, which calls the hypterterminal and initialice the COM-Port to 19200 Baud. By the way Hyperterm understand also the kermit-protocol. So you can exchange Data between a real CP/M Computer and a Windows computer. With the kermit.com inside YAZE-AG when yaze_bin.exe runs you can also communicate with a real CP/M computer. I tried higher transfer rates than 19200, but only 19200 or less works with a CP/M-computer !!! When you connect two PC-Computers with the serial chip which have a FIFO for 10 characters, you can go up to a baud rate of 110000. For example I have the following situation to develop for my Z280-System (called CPU280 by Reh Design (Tilmann Reh)): Notebook (Windows 7) Z280 - System .-----------------------. (CP/M 3) COM1| .------------. | +-------=-----| HYPER-Term | | Monitor |serial | `------------' | | |line | | .---------. | | .-----------. | | |CRT1 | | | notepad++ |-----=--------+ |CPU-UART-=-----+ | | Editor | | | | (Z280) | | `-----------' | eth0 | |CP/M-AUX-=-----+ | .-------. | | | |CRT2 | | | PUTTY |---------=-------+| `---------' | | `-------' | || | | `-----------------------' || keyboard | || | || LAN | Server (64 Bit Linux) || | .-----------------------. || | | | || | | +---------------=-------+| | | | .------. | eth0 | | | | |Samba |-=--------+ serial | | | `------' | line | | .-------------. | | | COM1| | YAZE-AG | | | +-------=-|AUX (CP/M 3)| | | | `-------------' | | | | .------. | | +-----| HD | | | `------' | `-----------------------' - I'am sitting at my Notebook. With notepad++ I edit C-sources which I put over CIFS/SMB with Samba on the Hard disk(HD) of the Linux-Server. - With the function "Mounting directories with Time Stamps" (described also in this document) I import the edit files into YAZE-AG. I have a connection over the SSH-Client PUTTY to a running YAZE-AG on the Linux-Server. So I can compile the C-sources with a make utility with the HI-C-Z280-Compiler inside YAZE-AG from my Notebook. (The HI-C-Compiler is very slow, but on the Linux-Server with a CPU clock of 2.66 GHz it is a little bit faster ) - The AUX device of the CP/M inside YAZE-AG is attached to /dev/ttyS0 (COM1) of the Linux-System. - At the Keyboard/Monitor of the Z280 system I start kermit (it uses AUX of CP/M 3 which is connected to the serial Port CRT2). I also start kermit inside YAZE-AG on the Linux-Server to transfere the compiled programm data from YAZE-AG on the Server to the Z280 system. - The software which I write for the Z280 uses the UART which is inside the Z280 CPU. I see the output at the UART of the Z280-programm in the Hyperterminal at my Notebook and so I can control the software in the Z280 system. 20.

It let you use the cursor keys of the PC in the command line of CP/M 3.1 and in Wordstar or other wordstar compatible editors. Also you can put "strings" on function-key and many more. Look to the PDF "yaze-keys.pdf" to see how the keytranslation works and how you use it. By default the keytranslation-table "yaze.ktt" is loaded by yaze-ag. There are 3 KTT-files: yaze.ktt, m2.ktt and sample.ktt. m2.ktt is for the editor in the Turbo-Modula-2. sample.ktt are samples. With the A:KTT.COM inside the emaultor you can change the ktt-file. The ktt-files are unter Unix/Linux or Windows, NOT inside the emulator. 2. January 2018 Andreas Gerlich (University of Ulm, Germany)   11. Wordstar with more than 25 lines: ===================================== Jon Saxton produce a patch (see A:CPM4WS4.Z80) for Wordstar 4.0 to set the columns and lines from the SCB (System Control Block) of CP/M 3.1. So you can use the xterm-terminal (or minntty.exe (Cygwin/Windows), or gnome-terminal (LinuxMint) or lxterminal (Raspbian)) with more than 25 lines. The columns and lines are read from the SCB and set in Wordstar bevor it initialize the screen. 1. You have to expand the gnome-terminal (under LinuxMint) to the 80 colomn and for example 53 lines and save it in the profile (or set up a desktop starter with the option "gnome-terminal --geometry=80x53"). 2. You have to set the colomns (#80) and new lines (#53) at system generation of CPM3.SYS and A:CPM3.COM. (The submit file "G.SUB" on drive P: produce after an interactive system generation the file A:CPM3.COM.) 3. The best way is to rename A:CPM3.COM to A:CPM3-53.COM when you have set #53 lines during system generation. 4. Then you have to start the CPM3-53.COM to start (cold boot) CP/M 3.1 with the new column and lines in the SCB. 5. Run Wordstar and you can edit with a screen of 53 lines. I'am have create a starter on the desktop with the options "--geometry=80x53". So a normal termnal have 25 lines and the terminal-emulator for yaze-ag starts with 53 lines. I export A:CPM3-53.COM with the W.COM utility to Unix/Linux/Windows into the $HOME/cpm directory and use this file in the desktop starter with the "-b" option ("boot file") of the "yaze" script ("yaze -b cpm3-53.com") to start yaze-ag with the boot file "cpm3-53.com" instead of "yaze-cpm3.boot". The command in my desktop starter for yaze-ag looks like this: "gnome-terminal --geometry=80x53 -x yaze -b cpm3_53-lines.boot" I use a terminal with 53 lines! The A:CPM3-53.com have I renamed to "cpm3_53-lines.boot" and is in the $HOME/cpm directory which uses the "yaze" shell script. The "-x" option say to the gnome-terminal that it have to execute the command after "-x" instead of the /bin/bash shell. ----------------- The CP/M system generation looks like this: P>g (start G.SUB on drive P: (BIOS3.ydsk)) P>mera P>gencpm CP/M 3.0 System Generation Copyright (C) 1982, Digital Research Default entries are shown in (parens). Default base is Hex, precede entry with # for decimal Use GENCPM.DAT for defaults (Y) ? RETURN Create a new GENCPM.DAT file (N) ? RETURN Display Load Map at Cold Boot (N) ? y <-- give "y" or "n" Number of console columns (#80) ? RETURN Number of lines in console page (#25) ? #53 <-- give #53 for dezimal 53 lines! Backspace echoes erased character (N) ? RETURN Then you have to give a lot of RETURNS until the following lines: ... ... Number of data buffers for drive P: (#0) ? RETURN Share buffer(s) with which drive (A:) ? RETURN Available space in 256 byte pages: TPA = 00F8H, Bank 0 = 0005H, Other banks = 0328H Accept new buffer definitions (Y) ? RETURN At this point you give also RETURN and then A:CPM3.COM will be produced! At the point "Create a new GENCPM.DAT file (N) ?" give never "y" because this produce a new GENCPM.DAT. But if you give at this point a "y" you can restore GENCPM.DAT from GENCPM.OK the backup of the original GENCPM.DAT. GENCPM.DAT is a very important file for system generation. 2. January 2018 Andreas Gerlich (University of Ulm, Germany)   12. Following files are in the yaze-ag package (yaze-ag-2.40.5.tar.gz): ======================================================================= MD5 checksum md5_yaze-ag-2.20 The md5 checksum file of the final release of version 2.20. With this md5 checksum file you can check all files. Use "md5sum -c md5_yaze-ag-2.20" to check all files (see "man md5sum"). md5_yaze-ag-2.12.1 The md5 checksum file of the final release of version 2.12.1. Documentation (in doc/ and doc_html/) index.html Click this file to read the documentaion. 00-INDEX.doc A brief index of the documentation of yaze-ag INSTALL-2.30.2 describes the install process of version 2.30.2 README-2.30.2 README to final release 2.30.2 yaze-ag.doc The documentation only of the new features of yaze-ag-2.40.5 yaze.1 Man page to yaze-ag cdm.1 Man page to cdm (CP/M Disk Manager) README_BIOS3_Z80 README of the CP/M 3.1 BIOS files (*.Z80) README_BOOTSYS README of the new CPM3.SYS loader BOOTSYS README-1.10 README of the features of the old version 1.06/1.10 yaze.doc The documentation of the old version 1.00 to 1.10 Makefiles Makefile_solaris Makefile for Solaris (copy it to Makefile) Makefile_linux Makefile for Linux (copy it to Makefile) Makefile_freebsd Makefile for FreeBSD (copy it to Makefile) Makefile_cygwin Makefile for Cygwin (copy it to Makefile) (cygwin is a unix like enviroment for windows) The different modules (I have made a lot of changes in all modules): yaze.c Source of the main yaze.h belonging to yaze.c mem_mmu.c Some definitions and routines for usage the emulated (new) MMU in YAZE-AG-2.30.2. mem_mmu.h The central definitions for memory access. All other (new) modules uses this definitions in dependence of -DMMU if defined or not. simz80.c The Z80 interpreter. I made a lot of changes for usage the MMU (over mem_mmu.h) because the memory access goes over the interface macros GetBYTE, GetWORD PutBYTE, PutWORD which are defined in mem_mmu.h. This macros uses the selected MMU-table to manipulate the Z80-memory. BUT I DON'T CHANGE THE ALGORITHM OF ANY Z80 INSTRUC- TION !!! I MADE THE CHANGES VERY CAREFULLY !!! The test utilities zexall.com and zexdoc.com works very well !!! Any instruction is OK !!! (see above "Optimizing") simz80.h Definitions of the Z80-Register and some fundamental macros for simz80.c and other modules. simz80.pl If you want to experiment with the Z80-simulator you (perl-file) can use this file. I have transfered all changes which I made in simz80.c !!! This perl-script produce a simz80.c with all changes I made. bios.c The yaze-bios with CP/M 3.1 extensions. It uses also GetBYTE, GetWORD, PutBYTE, PutWORD to manipulate the Z80 memory. The CP/M 3.1 extensions will be switched on if -DMMU is defined in the Makefile. monitor.c The monitor for yaze-ag. Now you can mount/unmount disk files under CP/M 3.1. You can mount/unmount UNIX directories to a CP/M drive, too. yaze.boot It contains Superdos a CP/M 2.2 replacement. I take it from yaze-1.10. It is used if -DBOOTSYS is NOT defined. You can also boot Superdos (CP/M 2.2) with yaze -l -1 -b yaze.boot yaze-cpm3.boot This file contains BOOTSYS + CPM3.SYS to start (new) CP/M 3.1. If -DBOOTSYS is defined this file will be loaded at 0100H instead of yaze.boot (CP/M 2.2). It is the same file like CPM3.COM on Drive A:. I transfer it to Unix/ Linux and name it yaze-cpm3.boot. It will be generated under CP/M 3.1 by P:Y.SUB with PIP CPM3.COM=BOOTSYS.COM,CPM3.SYS (If -DMMU is not defined while -DBOOTSYS is defined yaze-ag will exit when the CP/M 3.1 bios starts and uses funtions for the MMU or CP/M 3.1 of the yaze-bios.) .yazerc The startup file for yaze-ag (see above). The other files are the same as in the yaze-1.10 distribution. yaze-DISK-Files which are defined in .yazerc: A: BOOT_UTILS.ydsk BOOT disk with CCP.COM some ZINC- and other utilities. See 0-README.1ST for the contents of this drive. B: CPM3_SYS.ydsk Disk with all CP/M 3.1 utilities. The command HELP.COM gives help to all CP/M 3.1 utilities. (In the help file HELP.HLP I add the new section "YAZE-AG".) C: ./disksort/ This drive is connected to the (unix-)sub- directory ./disksort/ . It contains the source files of the DISKSORT project. (Look drive D:) D: DISKSORT.ydsk Contains the submit files and the make file to compile the DISKSORT project. This disk file will contain the compiled files (*.rel and DISKSORT.COM) when you compile the project. (see chapter 7. Mounting directories with Time Stamps) F: ZINC.ydsk A copy of the ZINC project from John Elliott G: TEST-UTILS-1.10.ydsk The test utilities of version yaze-1.10. This test utilities test the Z80 simulator (simz80.c). All changes in simz80.c are OK. H: HI-C-Z280-Compiler.ydsk A copy of the HI-C-Compiler. The Z280 Optimiser and Z280 Libs are from Stefan Nitschke. I: UNIXLIKE.ydsk UNIX like utilities. See UTOOL*.MAN and the *.DOC files. J: MMU-Utils.ydsk Here are some test utilties for the simulated MMU in yaze-ag. Use it only under CP/M 2.2 (yaze.boot) or CP/M 3.1 will be crash. Only MMUPRINT does NOT made any changes in the MMU, you can use it to see the status of the MMU under CP/M 3.1 . You start CP/M 2.2 with the options yaze -l -1 -b yaze.boot K: Kermit_SZRZ.ydsk Communications software to use a serial line: Kermit is a standard software. There are versions for DOS and Windows. Under Windows you can use HyperTerm. SZ/RZ uses the Zmodem protocol. L: spl.ydsk SPL development environment to compile .SPL files. SPL develops Peter Schorn in Switzerland. The files YWRITE.SPL and YREAD.SPL are in this disk which are compiled to A:W.COM and A:R.COM. M: Turbo-Modula-2.ydsk Modula 2 Compiler of Borland Try the file BIRTHDAY.COM it makes some calculations with your birthday. N: testdisk.ydsk testdisk P: BIOS3.ydsk The disks with which I developed the CP/M 3.1 bios which act as an interface to the yaze-bios. There is also the source of BOOTSYS (Sorry the comments are in the german language ;-)). 0-README.1ST declares the files containing in this disks. It is the same file like README_BIOS3_Z80. There is also a copy of ZPM3N10.PMA. On every disks are a file with the name 0-README.1ST. This file describes the contents of the disk.   13. Optimizing and speedtest: ============================= I made also some work for optimize in simz80.c. If you compile yaze-ag-2.30.2 without -DMMU and without -DBOOTSYS, yaze-ag-2.30.2 will be compiled like the last yaze version (yaze-1.10) with only 64K and the default use of CP/M 2.2 (yaze.boot). On my Notebook with 2,9 GHz (corei7) SAVAGE.COM needs: yaze-2.30.3 0.265 secs (with MMU) 4.0MHz Z80 65.000 secs Zexall.com needs: yaze-2.30.2 25.849 secs (with MMU) 4.0MHz Z80 11688.000 secs (reference, 3.25 h) That correlates rather a ~ 1808.65 MHz Z80 (with MMU) On my 2,66 GHz Linux Server YAZE-AG runs like a Z80 with 1.558 GHz ;-) (Zexall needs only 30 seconds against 3,25 hours on an original Z80 with 4 MHz!!!) Thats very good to compile/develop software for the Z280 system :-) (messured with unix command "time")   14. My old real Z80 System: =========================== I have at home an old Z80 ECB-Bus-Sytem (4Mhz) (1982-1989). The terminal is an another ECB-BUS-Card and is it's own Z80-System with a CRT-Chip from Motorola. To the ECB-Bus it schows like a 8251 Intel Chip and it is very fast. For some ECB-Bus cards (CPU-, RAM-, Floppy-Card) of this system exists a CP/M 3.1 implementation of a german company, but I made a lot of extensions. So I add some ECB-Bus cards: a RAM-disk with 1,2 MB, an EPROM-Disk with 256 KB, a CMOS-RAM-disk with 64KB and a battery (on this is CPM3.SYS), an ECB-Bus-Card as a harddisk interface to an OMTI 5510 (IBM-XT HD controller) with an old 5 MB HD ;-) , and a Card with a clock. I made the bios extension succesive for this new 4 drives and the clock. I think I have through this work a lot of practise to develop a CP/M 3.1 bios and this contribute the development of the bios and yaze-bios of yaze-ag. -- 3. January 2018 Dipl.-Ing.
