Here is another solution:

Look at page 6 for the parts list, you could build your own PIO encoder
board, you'll have to do some digging around for a 2376 keyboard
encoder, but places like netcomponents.com and freetradezone.com are
great sources for obsolete IC's

Hi Folks,
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.
It turns out that the keyboard uses little sponge pads to hold the
capacitive disks and they have biodegraded into dust.
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.
So let me turn to the experts and ask for advice and suggestions.
Please advise
