Refer back to Diagram 1 for clarification.
The installation process involves three steps:
1) Configuring your BIOS and setting the ZCPR2 options
2) Overlaying the CCP with ZCPR2 and the old BIOS with
the new BIOS in the SYSGEN Image
3) Placing the new SYSGEN Image onto the Operating
System tracks of the disk
ZCPR� i� t� b� installe� o� � workin� CP/� 2.� system�� Th� �
specific commercial software required to do this installation is:
1) A working CP/M 2.2 System
2) the MAC assembler of Digital Research
(another assembler may be substituted, but source
code modification to ZCPR2 may be required to do
an installation with an assembler other than MAC)
3) a debugger, like DDT, for the overlay process
4) a disk utility, like SYSGEN, to be used to place the
operating system image onto the operating system
tracks on disk
Th� non-commercia� softwar� require� fo� ZCPR� installatio� �
is:
CP/M 2.2 - based system (or ZCPR2 - based system)
8080 or Z80 microprocessor
32K bytes of memory
110K bytes of disk space for source, BAK, and HEX files
computer terminal
The hardware requirements for running ZCPR2 are:
ZCPR2 - based system
Z80 microprocessor
48K bytes of memory
110K bytes of disk space (recommended minimum)
