New toy, some questions..

For a birthday present, my girlfriend tracked down and bought me a Radio Shack PC-1 with cassette adapter (Both in orig boxes!). It compliments nicely the PC-2 and plotter I already have. After addition of four 1.35V zinc-air hearing aid batteries, it's humming along on my desk counting up by eights.. Does anyone still have software for this beastie? My other Q is converter programs. wav2bin (Sharp calc converter) supports it fine (its just a rebadged PC-1211) but the companion program bin2wav does not. Do other conversion programs exist? Are there any that run under *nixen? Any with source? I have tried contacting the fine folks at www.pocketmuseum.com, as they seem to be the author of the software mentioned already, to no avail (broken email addy). Jim
