I'm in the process of hooking up a Java microcontroller (JStick) to LM628. The LM628 theory looks quite appealing but I want to be sure there's someone out there I could count on for support just in case. National no longer provides tech support for LM628/9. Thanks

I have designed several boards with the LM628 chip, some with a 8051 (one and two non interpolating axis) and a ISA bus pc card with two interpolating axis. I would try to help you.

Best regards

I remember using that chip on a project many years ago. It had a few little quirks but you shouldn't have any problems with it. Plan your project well, and go at it one step at a time.

Motion control is fun...
