stepper driver

Colin Barker offered some zeta drives a while ago and I did not need them
then but might now. What model are they? I need something for 10 amps per
phase. I have an 850 inch ounce motor that I need to drive just as a
variable speed motor so any chopper driver that can take step or phase
signals would be fine.

I have the massive preset index module that came with the motor but it is
to big and heavy to use and is the old type with current limiting resistors
and not a chopper. If necessary, I can use the old power supply but would
much prefer a modern efficient type with built in p supply. Must be 110
volts and this is for a portable machine.

Please contact me directly if you have a driver to do this or a line on a
surplus supplier? spencer@...
