- By servo control IC's, I assume you mean motor (DC / stepper) controllers?
- If so, then Hewlett Packard also produce one, and it's fairly good, the
- HCTL-1100. I've played with these for the past 6 months, and they work
- well. If you hear of any others, I'd be interested to hear about them (I'm
- looking for controllers besides the HP chip.)
