According to some asking around, SparcStations-1's and -2's have an
other-wise unused timer available. The other timer is used for the 100Hz
(or whatever) interrupt.
We're in trying to mmap this puppy into user memory to use for timing, but
I would imagine others have done this already.
If you have, please let us know how it went & if you can share the source
(yes, we have a license).
