1969–1976
College of course.
1970–1990
I learned assembly in college. Actually it was mainly machine code. I went on to learning 4004, 8008, then started work in 1977. I spent 2 years doing intensive video game programming using just 8080 machine code and prom blasters. I guess you might call it assembly. Finally, we got to the point where we could afford an Intel MDS and stopped the hand coding.
1979–1980
I took a graduate course at Santa Clara University to learn Pascal. I used it for a short while developing a wafer fab control system.
1979–1980
1979–
I started studying Kernighan & Ritchie in 1979 with the intention of eventually using a higher level language for development work (I had been hand coding and using assembler). I didn't actually use it in a production environment until 1982 or so with a PC running Xenix for video games. Starting in 1984, I used it on Vax VMS and SunOS for real time vision processing systems and various control systems.
1980–1984
1980–1982
1980–1982
I used Basic to determine probabilities for various slot machines and video poker machines.
1982–
1983–1989
I designed a complete upright video game system based on the 8088. After getting the board in production, coding was done in assembler on an Intel MDS. Higher-level routines were later done in 'C' using a PC with Xenix. Games: Casino Blackjack, Wild Arrow, Golden Arrow, Jokers Wild (first Joker Poker ever made), Stud Poker, Jacks 'A' Pair, etc... (Nevada Gaming).
1983–
I tinkered with awk on a xenix PC and then used it some in the mid to late 80's for autonomous vehicle control language processing, mainly for quick prototyping before implementing Lex and Yacc. Later, I used it for language filtering systems in the same way in the 1990's. Then I discovered PERL (and PHP).
1987–1988
1987
We had a seminar series on Ada while I was working at FMC. Several DOD contracts we had used it but I never got on any of those projects.
1989–1991
I used PL/I working for Boeing on an 8051 system for the thrust reverser/landing gear control unit. Don't blame me! My job was to review the code and I told them it would happen. (!!! 3x) Later, I used it for technical reviews when working for some victims' attorney.
