...And a third example is DivisionMaster (http://www.divisionmaster.com) -
however, strictly speaking, none of these three is stepper control w/o a
computer, because all three have an embedded microcomputer that does the
"smarts" - a PIC in the case of DivisionMaster; don't know offhand what the
other two use.
