ZSIM is a Program that simulates a CP/M Z80 machine. It DOES NOT
simulate CP/M. But in the ZSIM package are included a PD CP/M
compatible operating system and a program to format CP/M disks, so you
can run CP/M programs.
WARNING: Don't let CP/M work on an MS-Dos disc as it may be destroyed.
WARNING: Even CP/M discs may be destroyed if they are in a format ZSIM
WARNING: does not recognize.
Use the software at your own risc. There is no warranty for the
program of any kind. The author takes no responsibility for any damage
caused by the program, either direct or indirect, to your hardware or
software. If you can't accept this restriction, please don't use ZSIM.
ZSIM consists of a Z80 emulator part and a CP/M 80 bios for 80x86 PC
compatible machines. The sources of the bios are included. I think
contrary to the CP/M bios a Z80 simulator might be used commercially
still today, so I don't include it's sources. The Z80 emulator is
contained in object form in Z80EMU.OBJ, a version with only the 8080
part of it in 8080EMU.OBJ. The 8080 Version is a few per cent faster,
as it hastn't to look after Z80 intricacies especially the V-Flag.
Don't try to disassemble it, in programming it I vastly used macros,
so the disassembler doesn't show much. But you can buy the sources of
the simulator from me. Anyway I don't think the emulator code can be
improved (show off, show off). Try your skills with the bios.
ZSIM was developed using Borland's TASM/TLINK.
ZSIM is almost wholly written in assembler, only the popup windows and
the parameter editor are written in Modula-2 (using the shareware
FMODULA2 Modula).
In the sources variable and label names are in English, comments are
in German. So if you are interested in some intricacies of the
bios get a German-English dictionary. Sorry.
By the way, excuse my English.
You may use the program ZSIM free of charge. This software may only be
duplicated and used for personal, non-commercial use. The software may
not be sold for profit. You may modify and improve those parts of the
program where the sources are included. But the executable program
must show my copyright message and a message that it has been
modified. Please include notes of your changes.
You may freely copy, distribute and use this program. If you like
ZSIM, a donation of $10 or any amount would be appreciated. Please
send a bill to the above address.
You want the sources of the Z80 Emulator, send a 50$ check to the
above address.
================
GETTING STARTED:
================
If you don't have a CP/M disc at hand you can test the Z80 emulator
anyway. Copy the files in the archive into a directory on your hard
disk. Format a 360K disc with CPMFRM.EXE. Type CPMFRM to get help. Be
sure that FORMAT.COM is in your PATH. The disc is only needed because
ZSIM requires a CP/M disc in the drive but it may be empty.
Then start ZSIM. It will load a CP/M compatible operating system from
CPMSYS.CPM (Superdos together with ZCPR) and if your PC has enough
memory (that is if CHKDSK shows at least 512000 free bytes) ZSIM loads
RAMDISC.CPM as ramdisc. If you want to boot from a real CP/M system
disc see in ZSIM.DOC for how to proceed.

READ ME | the file you're reading
In RAMDISC.CPM is a sample ramdisc that contains Ron Cain's Small C
Compiler, the VDE editor and the PPIP file copy program.
8080EMU.OBJ contains a version of the cpu emulator that understands
only 8080 code but runs a bit faster as it needn't worry about some
of the Z80's intricacies.
If you want to use Z80DOS instead of SUPERDOS simply copy Z80DOS.SYS
to CPMSYS.CPM.
I got SUPERDOS, Z80DOS and ZCPR from the SIMTEL20 [192.88.110.20] ftp
server (directory PD2:<CPM.xxx> xxx=BDOS,ZCPR). It contains a lot of
other CP/M software too.
HAVE FUN using ZSIM!
