True. But AFAIK the AT keyboard host interface was
never implemented in
TTL (it always used a programmed 8042 microcontroller), so it's a little
harder to build from scratch.
We used on our mc68000 boards a 68681 DUART & and some inverters as a
keyboard interface for xt/at. Was very simple. If anybody needs it, i could
dig it out again.
cheers,
