Lance,
I recently posted a thread on 8254 timer interrupts which Mike Luther and
Paul Dixon joined and did much to answer my question(s).
One part I hoped you (or others)would see and comment on is:
I tried to use the PB WAIT cmd with port &H40, but using mtimer
to measure results did not work well. I still think this sparsely
documented command (in PB35) could work??
I have seen this used for Vertical retrace timing; Will it work for machine
independant delays? What granularity and speed ?
