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?
