I've been searching around for some schematics for a wireless link for a TI 83/83+/84 calculator...yet in vain so far. There was something made back in 2000 called a radiolinc, however the site (fission2 labs) is down and I can't find any information on it. So if anyone has any details on how to make this or has any information or ideas for building this sort of wireless transmitter that'd be awesome. I figured this was probably the right site to ask...thanks!
