It's been a long time. Many apps were designed around the 55 msec 'tick' that was generated when the 8253 PIT rolled over at 64K. A fun project was twiddling with the PIT to generate, say, a 5 msec interrupt grabbing the interrupt for your nefarious purposes, but keeping track so the original ISR would still run at 55 msec. I sort of miss the old boxes where you could mess around with the hardware. I build a EPROM programmer that plugged into the parallel printer port. It had plenty of I/O for bit banging.
