Ok, I see.  Unfortunately, my motherboard does not have an ISA slot (why did
they have to get rid of those?).  I still have some feedback to EMC from the
error line of the gecko G320.  If the G320 gets off by more than 128 steps,
emc will know about it.

Your 30khz steprate on a 450mhz machine sounds better than I am getting on a
1.4ghz machine though.
