I actually own an original one (and some other goodies from my lispm time), I "just" need an adapter, but my electronics manufacturing / soldering talent is not adequate, sigh ;-0
If you're in the SF bay area, we might be able to get one put together... I've built several adapters for mice and keyboards, assuming the voltage levels are compatible it's mostly a matter of twiddling the right pins on a microcontroller. In return I would want to pick your brain about your lispm time :)
