I have had some success refilling vintage plotter pens for the Casio, Sharp, and Radio Shack printer plotters. After quite a few trials and errors, I might have finally solved the refill challenge.
Month: November 2024
I adapted the PB-770 maze program for the PB-1000 and created three types of printouts for the randomly generated mazes.
The Casio PB-770 was quite an impressive model given the release date. With a multi-line display and memory expansion options, this model was certainly a competitor to the Sharp offerings of the time.
I found a Casio PB-1000 and an MD-100 on an auction site. I have spent a few months with this pocket computer and it has become one of my favourites.
