Re-creating my first business computer experience using CP/M (ZPM) on a Vice emulated C128
A long time fanboy of the Commodore computers of the 80’s, Vic 20/C64/C128 – yes I owned all three of these in turn before jumping to the PC platform.
The ICL30 ran CP/M and came with a few business applications such as SuperCalc, WordStar and dBase installed on the 20MB Hard Disk. You can read more about this on my post covering my experiences with this machine here.
Creating a blank CMD-HD to use (linux)
With these somewhat nostalgic memories I decided I would try and get these same pieces of software running on the Vice C128 emulator to capture that first exposure to business computing.
This post runs through what has ended up being the main steps and setup to re-create a CP/M environment and contains links to the reference sources I have used to help me discover and learn about some of the computing options that where available back in the day, that I’d never even heard of but are now more easily accessible due to the very clever, wonderful people out in the world who have spend the time and energy to virtualise these retro computers.
Basic information on the setup I used to get this up and running.
Vice GTK C128 Emulator v3.7
JiffyDos ROMS v6.01
CMD-HD ROM v2.8
Commodore CPM 87
(CMD) HD-Tools
ctools (linux)
dd (100MB)
dd if=/dev/zero bs=512 count=0 seek=$[512*400] of=test100Mb.dhd
dd if=/dev/zero of=testfile bs=1024 count=102400
copy nul cmd-hd-a.dhd
used as the ’empty’ file method didn’t seem to work for me at the time, but dd reliably did
I used the 100MB sizing as a reasonable working size for the software I was looking to run as each 1581 drive would hold around 800K
D64 = 1541 = 170KB
D71 = 1571 = 340K
D81 = 1581 = 800K
SPORT.COM
sport /d8 or 10 /sf /c’cp1′
CMD-HD Partition types
1541
1571
1581
81-C (1581 CP/M)
NATV (CMD-HD native partition supports up to 16MB size)
PBUF – apparently never worked even on the original hardware, was supposed to be for printer buffering?
FORN – Foreign
SETUP of CMD-HD partitions
(Blank)
Create HD System
Attach disk image for drive
8tocmd-hd-tools.d64.Load and run “
CREATE SYS"from8. PressRETURNin the welcome screen.RESET TO INSTALLATION
Accept default with
RETURN. PressYto clear area below system.When finished, do a hard reset of the C64.
Create Partitions
Boot into CPM
SETUP NEW Partition Steps
Boot to HD-TOOLS and create a new 1581-C partition
REBOOT TO
CPM BOOT DISK in Drive 8 (will need SPORT.COM)
CMD-HD DISK in Drive 9 (It seems this is the only way to get it to format?)
BOOT CPM then use SPORT to set destination partition e.g. sport /d9 /sf /c’CP99′
Change Partitions (SPORT) in CPM
From BASIC

CP/M format the CP/M partitions
Copy over pip.com. sport.com. submit.com zde.com
CMD-HD Partition Table – unless noted these are all using the 1581-CPM partition type
#1 – MENU (1571) (NOW BOOTS TO MENU)!
#2 – CPM3-87 ++
#3 – CPMFAST
#4 – ZPM
#9 – HDTOOLS (1571)
#10 – WORDSTAR
#11 – DBASE2
#12 – SUPERCALC2
#20 – COBOL
#21 – TURBO PASCAL
#22 – LISP
#23 – MBASIC
