[Christopher] sent in his modded TI-83 calculator. (Hit the read link, a bug is broke the one I tried to embed) Besides the uh, racing stripes, he added a PS/2 port (though I see drivers for this mod are up on ticalc.org) and an integrated (cpu controlled) RGB backlight. The backlight is controlled with a programmable AND array that’s slaved off a pair of the CPU I/O lines. Just to top everything off, I poked around and found that you can overclock these puppies, as well as expand their memory. I’m hopeful that wetsanding and varnishing the thing 10 times smoothed out the paintbrush lines, but an inexpensive airbrush would yield much smoother results.
