Just seeing this old thread since it was bumped recently.
I've collected and discarded countless old ISA, MicroChannel, AGP, and other legacy cards since the 80's.
Joe showed an IRMA card in his first post, which is what prompted me to respond. Back in the mid-80's I interned (later hired, but didn't stay long) for ICOT Network Systems which was probably IRMA's biggest competitor in 3270 cards. I wrote the character generator software (in x86 assembler) for those cards. I still have a greenbar printout of that asm code somewhere. Preserved for posterity, as it was my first "commercial" software product that I wrote entirely by myself.
