I have only one thing to say about this idea: yuk! <grin> I would also have
to say that personally, I wouldn't want to write the various interrupt
handlers. Can you imagine what would happen when the thing crashed?

I think it might be better to use (if absolutely necessary) a PIC to handle
the keyboard. It would be better to use an 8041, as in the AT, but I have
no idea about prices.

This is getting worse and worse <grin>. Again, what happens when the 3041
crashes? I shudder to think... Interrupt latency takes on a whole new
