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.

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.
