I *suppose* you could hook each of the 16 KB
lines (assuming and 8x8
matrix) to an interrupt, and then create a table of values for any
combination. But, it seemed easier and more flexible to use a cross
point, especially since I also wanted to allow use of the original KB in
addition to the PS/2 KB.
Hmmm, I didn't know all of that :(
