Check out my optoisolated stepper controller on ftp.ee.ualberta.ca.  It is
a compressed tarfile named /pub/cookbook/unsorted/pc_stepr.tar.Z.  If you
can't deal with a compressed tarfile, let me know and I can send you a
zipfile or whatever.  This package includes schematic, PCB patter, parts
list, and high level instructions.  The card is 1.8" x 2.8".

This card makes it *really* simple to control a stepper using a PC or a
microcontroller.  Basically, you just set the control signals (TTL
compatible) to what you want and toggle the STEP input.  Control inputs
include HALF/FULL, DIRECTION, and ENABLE (allows cards to be connected in
parallel for multi-axis control).

I have (4) of these built that I was supposed to trade a guy for a surplus
X-Y table, but I haven't heard from him.  If he doesn't call soon, I will
be selling them.  I also still have some kits.  Have fun.
