Probably 1 GHz or greater, 256M or more of RAM. If you are using software step generation, for example with a parallel port driving the step motors, the main issue will not be the processor speed, but be the latency of the PC. This may require some fussing about with video cards, disabling SMI, or choosing a different motherboard. The wiki lists some known good motherboards: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Latency-Test Peter Wallace ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
