Wow, wish I'd had that info 10 years ago! I had an ST with malfunctioning keyboard which nobody could repair for me!
now people who has panasonic fx/wx/wsx/st/gt
with malfunctioning keyboard can fix it
Very cool mod, however it would be even better to just use caro's PS/2 keyboard controller on uber-cheap ATTiny pic.
Yes, its possible replace de 26 pin socket, adding a cpld and a ps2 socket.
