Vintage CPUs

My love for vintage technology knows no bounds. In my childhood, I learned to program using an Atari 400 at home, and various computers at libraries and schools such as the Apple II, Tandy, and IBM computers. I enjoy delving into the inner workings of classic IC chips like

  • CMOS Technology RCA 1802 (COSMAC) was used in spacecraft such as the Galileo probe. The Membership Card was my first introduction to vintage computer kits.
  • 8080 used in the Altair 8800 fascinated me with its history as the first commercially successful personal computer. An emulator was gifted to me at my housewarming party by a coworker who introduced me to vintage computing.
  • MOS Technologies 6502, found in Atari game consoles and computers, the Commodore 64, Apple II, Nintendo Entertainment System’s NES & SNES, and Ben Eaters 6502 Computer Kit. With new found knowledge, I was also able to restore my Atari 400 and program it in assembly.

Exploring the roots of modern computing not only satisfies my curiosity in programming in assembly and machine code but also provides valuable insights into the evolution of technology.
