I'm running my Bridgeport servo retrofit on a 100 MHz Pentium Classic
with 32 MB
of memory, on one of the first Intel ATX motherboards. The servo system
takes less
resources than software step pulse generation, so this is about the
absolute minimum.

I run all my hardware and software testing on a Pentium 133 Classic with
64 MB of
memory (because I recompile EMC quite often) and this is fine for use
with my
various PPMC and stepper controller board products. Again, they relieve the
CPU of some of the work of step pulse generation.

I have run some software step generation on a P-II 333 MHZ machine, and
it seemed
fine to me, for reasonable rates and step resolutions. This should be
totally acceptable
for running the BDI-2.20b on nearly all stepper systems, unless you are
using a high
microstepping factor.
