I have come across a few ICON chopper type stepper drive boards and power supplies. Does anyone have any info on these drives. The only thing I can find to id them on the boards is, they say ICON copyright 1989 made in U.S.A., Chopper 302-208-011 rev. 03. The power supplies are 68vdc 7a. I also got a couple of bipolar stepper motors with the ICON logo on them but they are made by Vexta model number PH296-02 and PH296-01. Any help would be appreciated.
