I need to time intervals in milliseconds on an AT clone.  I'm
sure the beast has some hardware counters that could be used
for such a job, but am not sure where they might be and how
to access them.

The box seems to be a very close hardware copy of the AT, aside
from running at a higher clock.  Solutions that are known to
work on a real AT will probably work here.

I am interested in details at the level of hardware I/O ports
or memory locations, and can write my own high-level language
interface to an assembly language routine.

Please respond by mail (if feasible), and I'll summarize any
interesting solutions for the net.

Thanks in advance,
Michael Cain
