We used a 386SX/16 to control an astronomical CCD camera- 16 bit
transfers every 25 microseconds or so (polling a 'ready' bit- no
interrupts). It runs perfectly in a dos session in the foreground. It
doesn't like running in the background at all :-). I've just put an
audible warning on the exposure timer, so I can leave it in the
background while the CCD grabs photons, then switch it back to the
foreground before it starts reading the data from the camera. It depends
a lot on the sort of data your gathering, and what you want to do while
you gather it...
