I too am rebuilding an Imsai 8080. I built several new ones in college (1977) and found one that needed some love. Everything is working and I have been scouring the web tubes for old S-100 cards.
I am currently trying to get my serial port to work. I am using my $4000 Mac Pro as a dumb terminal and have the Processor Technology SIO card. Not quite there yet with the basic communication, my RS232 memory is a bit rusty (now which one is the data set??)
I recently came across a S-100 card that has four serial ports on it. Professionally made, in excellent condition and absolutely no documentation. The only markings on this card are "C.E.P.C. 4-sio-2 Rev 2A"
I have been unable to figure out what the CEPC is. I cannot find any record of such a company and none of the S-100 archives out there have any reference to it or to a card referred to as 4-SIO-2.
Anyone remember anything about this thing?
