BACKGROUND

I bought my first computer when starting at the university. I wasn't so much into gaming, and what I was looking for was a powerful and yet affordable computer. The computer I chose was a CASIO FP-1100. It was a Z80 CPU based computer with 64kb RAM and a second CPU with 48kb RAM responsible for the video and graphics. I couldn't afford a color screen, and I ended up with a 12" green monitor. The machine was able to produce 16 colors if I remember correctly, but on my screen, it came out as shades of green. Later I also acquired a double disk station with 2 x 360kb disks. The machine could either run in a Casio Basic mode or full CP/M 2.2 system. I had several program packages, those I remember best was WordStar 3.3, dBase II, SuperCalc, PascalMT+, TurboPascal 3.
I had a few games, but my primary interest was in programming. I did many patches to CP/M and the software. I also wrote a few games and system tools. The computer was thrown away many years ago when it was still working, and I wish hadn't. I don't have formal training in electronics and computer other than a few programming courses (PASCAL) at the university. I made an early decision that I didn't want to make a professional career in computing, but keep it as a hobby, which I have to this day. I have later programmed for more advanced systems with GUI. I am too old for that now, so the RC2014 ecosystem enables me to go back and "play" in a more familiar environment.

The photo shows my main setup:

  • Six Slot Backplane
  • Z80 CPU + CLK, 20Mhz
  • 512K RAM/512K ROM
  • Compact Flash Drive
  • MC68B50 + CLK serial I/O card
Not beautiful, but functional and very stable.
