The two files in this ZIP file are disassembled CP/M 2.2.
CPM22.ASM : CP/M 2.2 in 8080 mnemonics
CPM22.Z80 : CP/M 2.2 in Z80 mnemonics
Both files claim to implement a fix that affects operation in a sector
deblocking environment. The Z80 version does not look to have been optimized
for the Z80, it just uses Z80 mnemonics.

The following list of corrections should be made to the Personal CP/M 8-bit
version 1.0 documentation.
Programmer's Guide
page 2-10
BDOS function 2
text says 'CONSOLE INPUT'
should be 'CONSOLE OUTPUT'
page 2-45
BDOS function 33
'Entry Parameters' add after Register C line:
'Register DE: FCB Address'
page 2-49
BDOS function 35
replace information about values returned in registers with:
'Random record field of FCB set'
System Guide
Section 2
References to the BDOS size being 1100h bytes are incorrect.
The BDOS code segment is 1000h bytes, and the BDOS data
segment is 00BFh bytes. With the standard distibution,
BDOSH.REL and BDOSL.REL will link these in a separate area
from the BDOS code segment. OEMs that purchase the source
can set an assembly-time switch that will make the data areas
part of the code segment so that it will all be linked as one
segment of 1100h bytes if the BDOS will execute in RAM.
page 4-15
BIOS function WRITE
Entry Parameters: Register C = 0: normal sector write
1: write to directory sector
2: write to the first sector
of a new data block

* Z80SIM - a Z80-CPU simulator
*
* Copyright (C) 1987-2006 by Udo Munk
*
* This modul contains a complex I/O-simulation for running
* CP/M 2, CP/M 3, MP/M...
* Please note this this doesn't emulate any hardware which
* ever existed, we've got all virtual circuits in here!
*
* History:
* 28-SEP-87 Development on TARGON/35 with AT&T Unix System V.3
* 19-MAY-89 Additions for CP/M 3.0 und MP/M
* 23-DEC-90 Ported to COHERENT 3.0
* 10-JUN-92 Some optimization done
* 25-JUN-92 Flush output of stdout only at every OUT to port 0
* 25-JUN-92 Comments in english and ported to COHERENT 4.0
* 05-OCT-06 modified to compile on modern POSIX OS's
* 18-NOV-06 added a second harddisk
*/
/*
* This module contains the I/O handlers for a simulation

* Used I/O ports:

* 0 - console status

* 2 - printer status
* 3 - printer data
*
* 4 - auxilary status

Usage:
z80asm -ofile -f[b|m|h] -l[file] -s[n|a] -x -v -dsymbol ... file ...
A maximum of 512 source files is allowed. If the filename of a source
doesn't have an extension the default extension ".asm" will be
concated. Source file names may have a path, the maximum length of
a full qualified filename is 2048 characters.
For relative paths the extension must be used, because all characters
after a "." would be used as extension!
Option o:
To override the default name of the output file. Without this option
the name of the output file becomes the name of the input file,
but with the extension ".bin". The output file may have a path,
the maximum length is limited to 2048 characters.
Option f:
Format of the output file:
-fb -> binary file
-fm -> binary file with Mostek header
-fh -> Intel hex
Option l:
Without this option no list file will be generated. With -l a list
file with the name of the source file but extension ".lis" will be
generated. An optional file name with path (2048 characters maximum)
may be added to this option.
Option s:
This option writes the unsorted symbol table (-s), sorted by name (-sn)
or sorted by address (-sa) into the list file. This option only works
together with option -l.
Option x:
Don't output data in pass 2 into object file for DEFS. This only works
if unallocated data isn't followed by any code or initialized data!
Usefull for CP/M BIOS's, where unallocated data doesn't need to be
part of the system image, if the complete image won't fit on the system
tracks.
Option v:
Verbose operation of the assembler.
Option d:
This option predefines symbols with a value of 0.
The number of this option is not limited in the command line.
Pseudo Operations:
Definition of symbols and allocation of memory:
ORG <expression> - set program address
<symbol> EQU <expression> - define constant symbol
<symbol> DEFL <expression> - define variable symbol
<symbol> DEFB <exp,'char',..> - write bytes in memory
<symbol> DEFW <exp,exp..> - write words (16 bits) in memory
<symbol> DEFM <'string'> - write character string in memory
<symbol> DEFS <expression> - reserve space in memory
Conditional assembly:
IFDEF <symbol> - assemble if symbol defined
IFNDEF <symbol> - assemble if symbol not defined
IFEQ <exp1,exp2> - assemble if equal
IFNEQ <exp1,exp2> - assemble if not equal
ELSE - else for all conditionals
ENDIF - end of conditional assembly
Manipulation of list file:
PAGE <expression> - number of lines/page
EJECT - skip to new page
LIST - listing on
NOLIST - listing off
TITLE <'string'> - define title for page header
Others:
INCLUDE <filename> - include another source file
PRINT <'string'> - print string to stdout in pass one

Quickstart to run CP/M and MP/M on the Z80-CPU simulation
1. Change to directory ~/z80pack/cpmsim/srcsim
make
make clean
This compiles the CPU and hardware emulation needed to run CP/M and MP/M.
2. Change to directory ~/z80pack/cpmsim/srccpm2
make
make clean
This compiles support programs (see below), installs named pipes and so on.
3. Make backup copies of your distribution disks!
cd ~/z80pack/cpmsim/disks/library
cp *.dsk ../backups
4. Change to directory ~/z80pack/cpmsim
cpm2 - run CP/M 2.2
cpm3 - run CP/M 3.0
mpm - this boots CP/M 2, run command mpm to boot MP/M 2
Usage of the support programs:
format: to create an empty disk image for the CP/M simulation.
input: format <a | b | c | d | i | j>
output: in directory disks files drivea.cpm, driveb.cpm,
drivec.cpm, drived.cpm, drivei.cpm and drivej.cpm
bin2hex:converts binary files to Intel hex.
receive:This is a process spawned by cpmsim. It reads from the named
pipe auxout and writes all input from the pipe to the file,
which is given as first argument. cpmsim spawns this process
with the output filename auxiliary.cpm. Inside the simulator
this pipe is connected to I/O-port 5, which is assigned
to the CP/M device PUN:. So everything you write from CP/M
to device PUN: goes into the file auxiliary.cpm on the
UNIX host.
send: This process is to send a file from the UNIX host to the
simulator. Type send <filename> &, and then run cpmsim.
The process writes all data from file into the named pipe
auxin, which is also connected to I/O-port 5, which is
assigned to the CP/M device RDR:. You may use this to
transfer a file from the UNIX host to the simulator.
Under CP/M type pip file=RDR: to read the data send from
the process on the UNIX host.
If you use PIP to transfer files between the UNIX host and the
simulator, you can only use ASCII files, because pip uses cntl-z
for EOF! To transfer a binary file from the UNIX host to the
simulator convert it to Intel hex format with bin2hex. This
can be converted back to a binary file under CP/M with the LOAD
command.
