    NAME
           yaze-ag - yet another z80 emulator by ag

    SYNOPSIS
           yaze  [-1]  [-v] [-bbootfile] [-lloadadr] [-pbasepage] [-sstartup]
           [-zZ3ENV] command...
           cpm ...
           z80 ...

    DESCRIPTION
           yaze-ag has been designed to provide an exact simulation of the Z80 mi−
           croprocessor  on a Unix system. In addition to the instruction set emu−
           lator, a CP/M basic i/o system is provided that can reference Unix  di−
           rectories  and Unix files containing images of CP/M disks.  When a gen−
           uine 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-/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
           allows 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 as−
           semble 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 BOOT-
           SYS.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 fol-
           lowing 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 re-
           locates 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 immediately 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 documentation in this directory.  This only happens if the di−
           rectory $HOME/cpm does not exists.
           Finally, it changes to $HOME/cpm and starts yaze_bin.  This is done ev−
           ery  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
                  create)  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
                  COMMANDS.

           -v     causes a summary of the system configuration to be displayed af−
                  ter loading.

           -b     gives  the name of a file to be loaded into the emulated proces−
                  sor'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 boot file is not  specified
                  with  the  -b  option,  yaze-ag looks firstly for the file yaze-
                  cpm3.boot in the current 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 replacement 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 follow−
                  ing 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 boot file is
                  loaded if a -l option is not present.

           -s     a file containing monitor commands that are to be  executed  be−
                  fore 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.

           clock  Display and set the clock rate

                  Without a parameter it displays the current clock rate.  With  a
                  parameter  (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
                  command into the yaze-ag startup file $HOME/cpm/.yazerc.
