=> 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.
But Tony, I can do everything with a $2 microcontroller...Why the
crosspoint IC? :oO
