I have one of these, a working (tried it, worked) and reassembled it as
Compupro CPU-Z. No interest here in programming 8088.
< I picked up a Compupro 816 computer yesterday and an external drive unit
<with a hard drive and an 8" floppy drive. I haven't brought it home yet so
Ok, It's an S100 crate so the box and it's contents can be very out of sync.
If it has the 816 card that means 8085 and 8088 cpus on one card and it ran
CPM-80, CPM-86, CDOS, CCPM and even MSDOS(odd io compared to PC)!
<I haven't taken more than a quick look at it. Can anyone tell be about the
<computer and drive? What CPU, speed, etc. What kind of operating system i
There were several variation of the cpu speed but the slowest was 8mhz on
the 8088 and the fastest was 10mhz. The 8085 runs ar 5/6mhz.
minimum configuration was:
CPU 816
interfacer 4
Disk 1 (or 1A)
128k static ram
8" dual drive DSDD
versions included:
512k M-drive (ram disk 512k)
SYSTEM SUPPORT (TOY clock, interrupt controllers)
Hard disks
The drive used a DISK1 floppy that was a DMA device using 765 controller.
Hard disks would have either been DISK2 (8" drives) or DISK3 (5.25 drives).
<uses, etc. I don't see a keyboard or video connectors so I assume it needs
<a terminal to talk to it. Does any have a pinout of the serial port so I
The idea of monitor and keyboard is a PCism.
<the floppy drive use hard sectored disks, etc etc, etc. I noticed that
<there are connectors for both a 5.25" and an 8" floppy drives and another
Yes that controller will do all sizes (can easily be hacked for 3.5"!) but
it's likely that it was used with 8" DSDD or 5.25 48tpi DSDD.
<for a hard drive on the back of the CPU box. Does anyone have a manual or
<the OS software for one of these?
I have both but, I'm time cramped for copying (can't do that volume at
work). Herb Johnson can help here to.
