- Repairing a 3.5″ Floppy Drive
I recently needed to read old 3.5″ floppy disks for a project and was able to quite easily repair an old 3.5″ floppy drive in an old laptop. - RS-232 Interface for the PC-2
The RS-232 interface for the Radio Shack PC-2 along with the CE-158 for the Sharp PC-1500 are difficult to find these days. These added possibilities to connect to printers, modems, save load programs faster and more. Luckily the CE-158X has been released. - Matching Game for the Tandy PC-6
I was curious how difficult it would be to program a simple game for the PC-6. I picked a rather simple concept to start with, a “matching” game. - 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.
