Re: A92: Keyboard for the TI-92?!
You can "remote control" the 92, already with flink, and I was reading
somewhere that if you f5, diamond, (, R, the calc sets itself to remote
control mode, so hooking one up would definately be possible...
btw, f5, diamond, (, R basically locks your calc up, (you can't turn it
off unless something hooked up to it does) so don't try it if you have
anything important...
