Build your own TI-59
This Design News story doesn't give much information about 'Daniel', who has evidently emulated a TI-59 with a PIC microprocessor. Unfortunately, most of the links seem to be broken as well. At least this Make magazine blog entry gives a few more pictures.
The multicolor LEDs are kind of an interesting touch, and what's the deal with that LCD display? Debugging? I am certainly in a pretty weak position to be critical of the utility of other peoples' free-time projects, but why a TI-59? It was a decent calculator for its time, but it is fairly easy to find one on Ebay, replace the inevitably dead & corroded batteries and have a working version of the real thing. Still, a pretty neat project.
