Generally, NO WAY! Consider that this is about 50,000 lines of mostly C++,
with one section in C, that has only been run on Unix-derived systems for a
couple of years. (It was ported to NT, but the results were not completely
satisfactory.)

Anyway, it requires a multitasking OS, with a real-time capability, as the actual
servo loop routines run as a real time process. Supposedly, the real-time
extensions to NT are about $2000 per machine, and the interrupt latency
was too high for this use. Linux's real-time patch has astonishingly low
interrupt latency, so a high cycle rate of the servo loops can be obtained
without slowing the system down too much.

The best user interface so far runs under X-windows, although the
java UI is supposed to be operating, again.

After getting this all going on Linux, I don't think the crew at NIST
will ever want to go back to NT.
