I built a kit version of the Kaypro 2 in 1983, and remember Intel assembly language, Wordstar, and so on. It came as a bare, unpopulated circuit board; I had to solder all the sockets for the chips and descrete components by hand. Soldered all my own floppy cables and interfaces, too. Good days; when you really had to know the architecture of the system to get along.
That was actually my second homegrown. The first was called a Quest Super-Elf, and it had a 8-bit RCA 1802 processor, and 4K of memory. I built it in 1981. It had only a hex keypad on the front. I wrote the programs in assembler, hand-assembled them into binary, transposed to hex, and entered them in on the hex keypad. I saved programs to cassette tapes. Good training I suppose, but it sure required patience. I still have the two mother-boards for those computers, framed and hanging in my office. Best Regards, John D.

Good old Z-80 code .... and swapping mini-floppies every time I used Wordstar. Many thanks! Bruce T. >>> Bruce T.

If you're going to be like that... I had a MITS Altair 8800 with 256 bytes of memory, where you would step through memory to then toggle bits on and off via sense switches beneath LEDs. I think we should stop there, rather than go back further, to desk calculators and comptometers. :-) Richard Sims The contents of this email are the property of PNC.
