YAZE-AG(1) Frank, John Saxton and AGL Hacks YAZE-AG(1) NAME yaze-ag - yet another z80 emulator by ag SYNOPSIS yaze [-1] [-v] [-bbootfile] [-lloadadr] [-pbasepage] [-sstartup] [-zZ3ENV] com- mand... cpm ... z80 ... DESCRIPTION yaze-ag has been designed to provide an exact simulation of the Z80 micro- processor on a Unix system. In addition to the instruction set emulator, a CP/M basic i/o system is provided that can reference Unix directories and Unix files containing images of CP/M disks. When a genuine CP/M operating system (ccp + bdos) or a clone system is loaded into the emulator, a com- plete CP/M system is available, running on a Unix-/Linux-/RaspberryPi-/Mac-/Windows-Host. yaze-ag-2.51.3 is a further development of yaze-1.10. New in yaze-ag is the emulated Memory Management Unit (MMU) and the BIOS that supports CP/M 3.1 or ZPM3 (boot file yaze-cpm3.boot) which is used in yaze-ag. You can still run the CP/M 2.2 replacement "SuperDos" (boot file yaze.boot) in yaze-ag if you want. New in version 2.40.5 was the key translation module. So you can use e.g. the cursor keys and function keys in the CP/M command line or when Wordstar is running. Look at the files $HOME/cpm/*.ktt on the host. New in version 2.51.1 was the possibility to define a clock rate. This al- lows you to run the emulator e.g. with 4.0 MHz. Further there is a "window size handler" in the binary of yaze-ag. This handler determines the coordinates of the used Terminal emulator (e.g. xterm, gnome-terminal, mintty (Cygwin/Windows), ...). So the lines and columns variables in the System Control Block (SCB) of CP/M-3 are set by this handler. The patched Wordstar 4.00 (see drive A:) and the CP/M-3-Utilities (e.g. TYPE.COM, 3DIR.COM, DIR.COM, ...) uses this two variables in the SCB via the standardized BDOS3-Interface (call to 0005H) to setup the screen. Further you can test the speed of the Z80 core with the submit file "A:TESTZEX.SUB". It runs ZEXALL.COM and measure up the time how it's need and prints the speed at the end of the submit file. New in version 2.51.2 is the Macro Assembler "ZSM4". It's a Z80/Z180/Z280 Assembler. The licence is the GPLv2 (GNU GENERAL PUBLIC LICENSE Version 2, June 1991). The project page is "https://github.com/hperaza/ZSM4". The source files of this Assembler can be mounted on drive O:. This Assembler is now the standard for assemble BOOTSYS and the BIOS3-Z80-files for YAZE- AG (see drive P:). Further with the flag "-?" you can print the usage, the features of yaze-ag and at last it prints the copyright report. New in version 2.51.3 is "BOOTSYS version 2.00". When you call BOOTSYS.COM it tries to open A:CPM3.SYS. Where A: is the drive which is defined as the default drive in BOOTSYS.MAC (see drive P:). You can define a drive as a parameter (e.g. "bootsys p:" (the colon ist necessary)). BOOTSYS tries to open CPM3.SYS on that drive. After load of CPM3.SYS it relocates CPM3.SYS and starts CP/M 3.1 (cold boot). An another way to load CPM 3.1 is to generate a CPM3.COM with the following command: A>pip cpm3.com=bootsys.com,cpm3.sys You simple append CPM3.SYS after BOOTSYS.COM and save both in CPM3.COM. When you call CPM3.COM BOOTSYS tests if a CPM3.SYS is appended and relo- cates at once CPM3.SYS and starts CP/M 3.1 (cold boot). The boot file "yaze-cpm3.boot" which is load when you start YAZE-AG is identical with A:CPM3.COM. yaze is a shell script. It is used to start yaze-ag. It first tests if the startup file .yazerc is in the current directory. If there is one, it imme- diately starts yaze_bin the binary of the Z80 emulator. If .yazerc does not exist, it tests if the directory $HOME/cpm exists. If not, it creates $HOME/cpm. Then it copies some yaze-disks-files (.ydsk) to $HOME/cpm which are necessary for running yaze-ag with CP/M 3.1 or ZPM3. Then it creates $HOME/cpm/doc_html and sets links to the complete documen- tation in this directory. This only happens if the directory $HOME/cpm does not exists. Finally, it changes to $HOME/cpm and starts yaze_bin. This is done every time you start the shell script yaze and if .yazerc is not present in the current directory. yaze-ag can also be started with z80 or cpm. They are symbolic links to the shell script yaze. The older documentation is contained in the file yaze.doc (version yaze-1.10) and the new features until yaze-ag-2.51.3 describes the file yaze-ag.doc (see $HOME/cpm/doc_html/index.html). OPTIONS -? prints the Usage, the Features and the Copyrights. -1 set sector size to 128 bytes for all disks (only CP/M 3.1). If you create a disk file under the yaze-ag monitor or with the cdm(1) utility and you use the default sectors per track (see cre- ate) the sector size is also set to 2048 bytes (only CP/M 3.1). If you use software like a disk edit utility under CP/M 3.1 it can be necessary to set the sector size to 128 bytes. See also the monitor command 128 above in the section MONITOR COM- MANDS. -v causes a summary of the system configuration to be displayed after loading. -b gives the name of a file to be loaded into the emulated processor's ram before the emulation is started. The file is loaded at the ad- dress given by the -l option, if one is present, or else at the basepage (see -p). If a boot file is not specified with the -b op- tion, yaze-ag looks firstly for the file yaze-cpm3.boot in the cur- rent directory, then in /usr/local/lib/yaze to boot CP/M 3.1. If yaze-ag is compiled without the flag -DBOOTSYS yaze-ag looks for the file yaze.boot (instead of yaze-cpm3.boot) to boot the CP/M 2.2 re- placement Superdos. -l the hexadecimal address at which to load and start the bootstrap file, if a separate bootstrap is necessary. If you want to run CP/M 2.2 while yaze-ag is compiled to load yaze- cpm3.boot (CP/M 3.1) you can start yaze-ag with the following op- tions: yaze -l -1 -b yaze.boot -p the top 2 hex digits of the location of the CP/M console command processor (CP/M 2.2). Also the location to which boot file is loaded if a -l option is not present. -s a file containing monitor commands that are to be executed before starting the emulator. If no -s option is present, .yazerc from the current directory or from the user's home directory ($HOME/cpm) is taken. -z the hexadecimal address in the emulated processor's ram of a 1KByte area that should be reserved for use by an extended CP/M clone such as ZCPR3. MONITOR COMMANDS When the emulator is started it executes commands first from the startup file ".yazerc", then from the tail of the command line (any strings which follow the options) and then from the tty if neither the startup file nor the command line included a "go" command. Control can be returned to the monitor by executing the CP/M sys.com command or, if yaze was compiled with -DDEBUG, by sending it a SIGINT signal. Command names can be shortened to unique abbreviations. If yaze-ag was compiled with GNU Readline, command-line editing, filename completion and history recall are available - see the readline documentation. The monitor commands are described with more details in the file yaze.doc. The new commands '128' and 'clock' are described in yaze-ag.doc. help Display a command list help cmd Give details about cmd attach Attach CP/M device to a Unix file/device clock Display and set the clock rate Without a parameter it displays the current clock rate. With a para- meter (for example 4000 for 4.0 MHz) the clock rate will be set. The parameter "0" returns to "max speed". If you want to set a permanent clock rate you can put a clock com- mand into the yaze-ag startup file $HOME/cpm/.yazerc. detach Detach CP/M device from file setaccess Turns on/off access time stamps for mounted directories mount Mount a Unix file or directory as a CP/M disk remount Remount a CP/M disk umount Unmount a CP/M disk create Create a new disk 128 Set sector size to 128 for all disks (only CP/M 3.1). To reverse this option you have to restart yaze-ag. interrupt Set user interrupt key go Start/Continue CP/M execution ! Execute a Unix command quit Terminate yaze time Display elapsed time since last `time' command SUPPORTED OPERATING SYSTEMS Yaze-ag-2.51.3 can be compiled under all unix or unix-like operating sys- tems. yaze-ag-2.51.3 are tested with: Solaris cc and gcc (SparcV9 and X86_64) Linux gcc (x86_64, x86_32, ARM6, ARM7 and ARM8) Raspberry Pi OS (Linux, Debian) Raspberry Pi 1 (ARM1176JZF-S, single core, 32 bit) Raspberry Pi 2 model B (Cortex-A7, quad core, 32 bit) Raspberry Pi 3 model B (Cortex-A53, quad core, 32 & 64 bit) Raspberry Pi 3 model B+ (Cortex-A53, quad core, 32 & 64 bit) Raspberry Pi 4 model B (Cortex-A72, quad core, 32 & 64 bit) FreeBSD clang (OPNsense) MacOS-X gcc ?
