I don't have a Mod IV. But if I build something here in Brazil, will you
be able to duplicate it there?
Are crosspoint swithc ICs still easily available? (It seems that so many
useful ICs are no longer made ;-(). If so,e it would seem to be posisble
to use one of those to simulate the keyswithc matrix for just avout any
swithc-type keyboard. Add a microcotnroller to decode the PS/2 keyboard
signal then if you detect akey-down code close the appropriate swtich in
the crosspoint array, if you detect a key-up contd open it. OK, there may
be a little more work for keys that were originally mechancially locking,
but that's essentially it, I think.
