I've called both Signetics >and Exar. Neither produces a modern replacement. 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.) > -Tod Simon. -- +--------------- Simon Cocking, sgc@yoyo.cc.monash.edu.au -------- /// -+ | Robotics & Digital Technology / GAUnix Group /// | | Monash University \\\/// | +------------------------- Melbourne, Australia. ------------- \XX/ ----+
