RE: HP 71B RAM: has anybody big ones to sell?
My card-reader-port RAM module is 96KB from CMT. CMT did in fact offer up to 160KB, and I drooled over it, but 96KB is all I felt I could afford at the time. Later I added a 64KB front-port ram module. I never ran out of RAM, but I probably had it 80 or 90% full, mostly with huge data arrays. There was one project where I formed Intel Hex files up to 384KB and transferred them to the PC over RS-232; but since I didn't have enough RAM to do it all at once, I sent each line as it was formed, and a GWBASIC program on the PC tacked it onto the end of the file being built on the hard disc.
