NAME
yaze-ag - yet another z80 emulator by ag
SYNOPSIS
yaze [-1] [-v] [-bbootfile] [-lloadadr] [-pbasepage] [-sstartup]
[-zZ3ENV] command...
cpm ...
z80 ...
DESCRIPTION
yaze-ag is designed to provide an exact simulation of the
Z80 microprocessor on a Unix system. In addition to the
instruction-set emulator, a CP/M basic i/o system is pro−
vided 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 complete CP/M system is available,
running on a Unix host.
yaze-ag-2.10 is a further development of yaze-1.10. New in
yaze-ag is the emulated Memory Management Unit (MMU) and
the BIOS which supports CP/M 3.1 or ZPM3 which is used in
yaze-ag. You can still run CP/M 2.2 or SuperDos (a CP/M
2.2 replacement) in yaze-ag if you want.
yaze is a shell script. It is used to start yaze-ag. It
tests firstly if the startup file .yazerc is in the direc−
tory of `pwd`. If there is one it starts at once yaze_bin
the binary of the Z80 emulator.
If no .yazerc exists it tests if the directory $HOME/cpm
exists. If not it creates $HOME/cpm. Then it copies some
yaze-disks into $HOME/cpm which are necessary for running
yaze-ag with CP/M 3.1 respectively ZPM3. Then it creates
$HOME/cpm/doc and sets links in that directory to the com−
plete documentation. This will be done only if no
$HOME/cpm directory exists.
At last it changes to $HOME/cpm and starts yaze_bin. This
will be done every time you starts the shell script yaze
and if there is no .yazerc in the `pwd`.
yaze-ag can also be started with z80 or cpm. They are
links to the shell script yaze.
The complete documentation is contained in the file
yaze.doc and the new features of yaze-ag-2.01 describes
the file yaze-ag.doc (see $HOME/cpm/doc).
OPTIONS
-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 create) the sektor 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 sektor size
to 128 bytes.
See also the monitor command 128 above in the sec−
tion MONITOR COMMANDS.
-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 emu−
lated processor's ram before the emulation is
started. The file is loaded at the address given
by the -l option, if one is present, or else at the
basepage (see -p). If a bootfile is not specified
with the -b option, yaze-ag looks for the file
yaze-cpm3.boot in the current directory first, 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 replacement Super−
Dos.
-l the hexadecimal address at which to load and start
the bootstrap file, if a separate bootstrap is nec−
essary.
If you want to run CP/M 2.2 while yaze-ag is com−
piled to load yaze-cpm3.boot (CP/M 3.1) you can
start yaze-ag with the options
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 bootfile 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 direc−
tory or from the user's home directory 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, 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 a unique abbreviation.
If yaze-ag was compiled with GNU Readline, command-line
editing, filename completion and history recall are avail−
able - see the readline documentation.
The monitor commands are described in more detail in the
file yaze.doc. The command '128' is described in
yaze-ag.doc.
