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.

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.
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.
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.
I recently tried HF packet using a vintage Kantronics KAM All Mode TNC and the FT-991A. I used an RJ45 A/B switch to be able to switch between either port of the KAM or between the KAM and my KPC-3.
I recently acquired a classic “Model T” laptop, recapped it, and started experimenting with BASIC and 8085 Assembly.
Using a PC-2 pocket computer to print a QSL card was an interesting project to test using BASIC and a 4 color plotter.
I took my Radio Shack PC-2 (Sharp PC-1500) out of the archive and restored a Sharp CE-150 plotter / cassette interface. I was able to connect the PC-2 to a TNC and print out APRS traffic.
PE1NNZ has updated the firmware (beta version) on the (tr)uSDX to add audio over USB. This allows for digital modes such as FT8 over USB without separate audio cables.
The Yaesu FT5D’s built in GPS can be connected to a PC for off grid time sync. All that is needed is a data cable and Meinberg NTP.
