The Bus is some sort of lab instrumentation and control. I am not sure what
it is called. It is familiar with me too. I have seen quite a few similar
cards in the past.

PS Nice to see you back. Nice MDS you got. What cards?
8080 CPU, monitor card, 2x 16k memory cards, 202 double density floppy
controller (2 cards) and ICE-80 pod with two card controller set. But the
coolest card is a Zendex model 908 EPROM programmer card. It's a Maultibus
card but it's taller than normal and sticks out of the top of the shassis.
Along the top of the card it has 8 ZIF sockets for EPROMs. It can program 8
EPROMs (2716, 2732 or 2732A) at one time. BUT you can also use it as a
standalone programmer. You can take it out of the chassis and connect it to
the computer via RS-232, connect a 5V power supply and operate it that way.
I did get the software and manuals for it too. :-) I'll take a picture of
the Zendex card and post it this afternoon. I'll post it at

Software: Besides ISIS-II, I got MS BASIC (version 1.0), PL/M-80
compiler, ASM-80 Macro-Assembler. Games: StarTrek Version 2.0), Othell(o),
chess, advent(ure), master(mind) and black box. Utilities: ICE 80, ICE 85,
ICE 48, UPM, and ZPP for operating the EPROM programmer.
BTW the label on it says that it's a model MDS-888. Does anyone know
exactly what an 888 is?
