- SLOW.COM
- uses the timer click interupt to slow down the AT, it sets up a
- user routine to be called on each click (interupt 1Ch), the user routine
- just does a delay loop, interupts are enabled during the loop so interupt
- driven devices like the keyboard still work, but the machine seems to be
- slowed down (even though it's running at full speed with just a lot of idle
- time). I set the values in the delay loop to come reasonably close to the
- speed of a normal PC. SLOW.COM will only work with programs that run under
- dos and do not disable the timer interupt or the user vector for timer.
-
- NOSLOW.COM
- revectors the user vector for timer back to the IRET in the bios so
- that the AT runs at full speed again.

- When I get an AT tech ref I will put together a SLOW.COM that works with just
- about anything.
