Re: time for microprocessors!

Hi Ron,

how about Cybernetic Microsystems CY545? "High Performance Stepper
System Controller"

http://www.controlchips.com/

I've used the old CY525 (yes, and the old CY512 and even the 500) to
drive a stepper from a parallel port before, and I plan (I've bought the
parts) to build a '545 one for 4-channel CNC. Expensive, a little.
Yes, I'd like to know what FlashCut is doing in their box!

Warm up the wire wrap gun!
