What would be the best way to implement a 16-bit bidirectional IO port on the AT bus? Would one just use a pair of 8255s in tandem, or is there a better PPI to use for 16-bit stuff that my substandard google-fu isn't sending me to?
(I assume that a 16-bit port read on the AT bus would be about twice as fast as a pair of 8-bit reads, right?)
