Ok, I am going to try and settle this stop-and-go issue today. I am
running EMC on a PIII 600mhz machine. I just got a 2nd PCI parallel
port card. I will install it today, hook up my digital oscilloscope
to the spindle I/O line and also to one of the axis step output lines
and see how out of sync the RT and non-RT sections of EMC are on my
machine. I will report my results.

Thanks,

Rick
