Well, there are other places these resistance-limited motors are used, 
but they invariably trade performance
for cutting a few more cents out of the driver circuit.

I'm not an expert on these driver chips, and don't even know what is 
making the drive signals to them in
your case.

Gag!  1980 technology at it's worst.  Any good bipolar microstepping 
driver will inprove things, and should be able to be used later
with better motors.
