It's been interesting taking out my old CP/M stuff
and getting it
operational again.
My system uses an 8bit TTL Keytronics Capacitive Sense keyboard. It was
operational for about an hour and then it quit.
So I went looking for an old 8b TTL replacement keyboard. So far no luck.
I also looked for a black box solution that would take an AT or PS/2
keyboard and convert it to a parallel port output. So far no luck.
Jim Brain has a microcontroller setup for doing this. I use it to convert
a PS/2 keyboard to parallel ASCII for my Vector Graphics machine. His
microcontroller solution outputs both parallel and serial output
simultaneously, so you can use either.
Drop Jim an eMail. I can vouch that the thing works a charm. (In my case
he just blew in the software into a ATMEGA8 and I built the circuit
myself, with copious help from him and other friends). But he's an
extremely skilled builder in his own right and would undoubtedly put it
together for you at a very reasonable price.
His eMail address is:
j brain AT brain DOT com
Replace AT and DOT as appropriate, and remove all spaces, including the
one between j and brain.
