I explore the TI-92 Plus (and similar) TI graphing calculators after a few simple repairs as well as introduce the PCUI (Pocket Computer Universal Interface) support for these calculators.

I began development of a Universal Pocket Computer Interface for use with Sharp, Casio, and Texas Instruments pocket computers and graphing calculators.
The Casio FX-702P was Casio’s first BASIC programmable pocket computer. The associated printer, the FP-10 mini electrostatic printer is quite an experience.
The Casio FX-750P is one of several pocket computers which utilized removable RAM Cards for quickly swapping programs and/or data.
The Casio FX-880P paired with the FA-6 expansion is quite capable for various purposes. As an experiment, I ported the banner and maze programs and tried the globe program as well.
The PB-2000C was the first pocket computer I have used which supports programming in C. There are both benefits and drawbacks to this model compared to the Casio PB-1000.
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.
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.
