Is there a kind soul out there who knows how to use the interrupt
system to catch 8520 timer interrupts? Spercifically, I want to be able 
to have a program that is interrupted 400-500 times a second and during
the interrupt have a quick look at the parallel port
and plot a couple of points in a bitmap.
 I can read the port
no problem, but at the moment am using an awful busy loop to watch
the timer. The solution should preferably use an absolute minimum of
assembler code and maximize the amount of C.
Thanks extremely.
