It certainly seems to have a load of memory chips in it! But I didn't <really try to tally the total amount. the base board has 2mb and there are two daughter boards one for the network (has 7990 lance chip) and the otehr is more memory. <Do you have a wiretable from the 60-pin to hard and floppy connectors? Iff the top of my head no, it's not that complex though. finding the 60 pin connector is the challenge. It's then broken down to the 34pin for the floppy, 43pin for the HD and the 22pin for the HD. <That 15-pin CRT/keyboard/mouse sounds an awful lot like the Rainbow <setup. Could I be so lucky? Maybe, I forget the cable and monitor used. there were both color and monochrome. The cable for the rainbow may not be useable! I don't have graphic consoles for mine so cables and tubes are a dim memory. <Heh heh! Hope they are not the nuisance that house flies are! Not likely, but fun. This will help with the monitor command the VS2000 is a subset of the vs3100 that would come later.
