I have for sale Mel's curcuit board, software, two steppers, and my proto type hand control. Have decided not to pursue this project. Purchased board in March of 2000 (S/N 2000.35). Never got around to using it. I did connect the board to a computer and with software running, it did work. One of the four push button switces on the hand control won't respond. This board does not have field rotator chip.
Steppers are Astrosyn 10v 1.8 deg/step unipolar with 45 in/oz tourque. Software supplied with the board ver 3/18/2000. I will also include an interface cable.
$65 US shipped via USPS check or MO fine.
Thanks for looking, Walter
