Compupro computer questions

Hi,

  I finally brought home the Compupro CPU box. I'm surprised how clean it
is. It looks like new. The only thing I found wrong so far is one wire
broken off of the backup battery holder. Here's what's in it:
 
 21 slot backplane, #194 Disk 3 card (hard drive controller), Disk 1A card
(5 1/4 and 8" floppy drive controller), #187 Interfacer 4 card (parallel
and triple serial ports), #162 System Support 1 card (serial port to
terminal, interupt controller, RTC, Math Co, 4K SRAM, etc), CPU 8085/88
card (both 8088 and 8085 CPUs), #816 RAM 22 card (with 256K SRAM), two RAM
23 cards with 128K SRAM each.

   I dug through my manuals and found manuals for the Interfacer 4, RAM 23,
CPU 8085/88 and System Support 1 cards. I still need manuals for the
chassis, RAM 22 and both disk controller cards. BTW I have extra copies of
the above 4 manuals. I'll trade them for the manuals I need.

   There's no red switch or anything marked "speed" on this card. FWIW the
CPUs are 8088-1 and D8085AH-1.

   I haven't brought home the drive box so I don't know what's in it yet.

   OK It's listed above. Thanks.
