Rodney, Just a few years after MIT's was on a cover there were Many uP (microprocessor) SBC and Systems. I had many of them and programmed them in assembly and many HLL. It was a great time to be growing up concurrently with retail technology release. Learning about uPs got me my start at IBM and a 30 year career. Great timing (for me). These are all great memories! BTW, along with SBC for many uP. I chose the Exidy Sorcerer (Z80) and then Atari and Amiga as growing up Systems. I skipped TRS 80 and Apple for many reasons. Amiga turned into the ARM team (or Atari) and was connected to many future trends. I used many 8085 and industry versions a uP and also some TI DSP which sprung from my early TI SBC. They didn't have ARM RISC yet (when I started to play) But my IBM department got one of the 1st RISC machines which became IBM's Power Series. Oh, and before it all (at IBM) I worked with an IBM 5110 which was an emulated 360 running Basic and APL without OS. :-D I'm not looking backward, I think TriLUG has a PDP guy come in with an emulator and I just chuckled to myself Why! :-D
