Vintage Computing

Experiences & Restoration

  • Tandy PC-7 Pocket Computer
    Although this is my least favourite of the Radio Shack line of pocket computers, it is the most nostalgic for me, as it is the only one I actually owned back when these were sold.
  • Loading Programs from WAV Files
    With a bit of organization, you can avoid the frustrations of loading saved programs (wav files) into pocket computers or other vintage computers.
  • Tandy PC-4 Pocket Computer
    I recently acquired the PC-4 printer and cassette modules and wrote a version of my banner program for this model pocket computer. With only 544 bytes available, it was the most challenging version to code.
  • TRS-80 PC-1 Pocket Computer
    Recently I’ve been curious about the TRS-80 Pocket Computer (the PC-1), the first pocket computer Radio Shack sold. I was able to find one on eBay and replace the LCD.
  • Tandy PC-6 Pocket Computer
    The PC-6 was the best (in my opinion) rebadged Casio pocket computer Radio Shack sold. I built a cable to connect the PC-6 to the FP-12S printer and updated my banner program using only 909 bytes of memory.
  • TRS-80 Model 100 with the KPC-3
    I was able to solve an issue connecting a TRS-80 Model 100 to a Kantronics KPC-3 TNC.
  • Connecting the TP-10 Printer to the PC-2
    After successfully connecting a TP-10 to the Model 100, I did the same with the PC-2. I also updated the banner program for the PC-2. This gives the PC-2 the ability to print without needing those expensive plotter pens.
  • Improved Banner Program for the TRS-80 Model 100
    After getting the TP-10 printer working with the Model 100, I set out to improve the banner program I wrote for the PC-8.
  • TP-10 Thermal Printer
    I found a great printer for the Model 100, the TP-10. This printer is thermal and uses 4 1/8″ paper. It has a serial connection and I’ve updated the banner program as an example of it’s capabilities.
  • Tandy PC-8 Pocket Computer
    I found the pocket computer model on eBay that I wanted as a kid, but couldn’t get. I repaired the printer cassette interface for it, and wrote a banner program using only 964 bytes of RAM.
