I hope this fits your expectations: Bob Lash and I go back to Palo Alto High School where we both graduated class of 1975. We used to hang out in the math lab area which was near one of the terminal rooms housing ASR 33's connected to HP 2000F and HP 3000 computers running basic. I was impressed with Bob's wire wrapped TTL microprogrammable machine he designed and built. I was an early Altair owner (#220218) but I soon tired of front panel switches and wire wrapped my own CPU board with EPROM monitor and video display from Lee Felsenstein's company (I forget the name). I remember how 8K static ram boards were sooo much memory back then. I actually did type in a 2K assembly program once for playing gomoku which worked pretty well. Since then, I got my B.S. and M.S. from UC Berkeley in EECS. I was in the original class David Patterson taught where we designed RISC I (and later RISC II). I ported the Steve Johnson portable C compiler to RISC, wrote an assembler and peephole optimizer, instruction level simulator and got dynamic instruction traces for my master's project. Later I joined CSRG and worked on Berkeley UNIX 4.2, 4.3, and ported 4.4 to a DEC 5000/200 (Mips R3000).
