Mmm, ISA is an old bus, with a quite slow data rate, bus clocking is at 7 mhz. Given the base thread requirements of doing real time step/dir controls, I don't believe a usable system could be built on the ISA bus. EMC, generally speaking, can use every megahertz of the cpu it can get because that in turn makes the speed increments ever finer at the high speed end of the range, which in turn helps the motors accelerate and decelerate smoothly. My own box is pci/agp, has an XP-1400 Athlon in it, on a Mach Speed board, and while that cpu cooks along at 170F on a biostar board running it at 1400mhz, on the Mach-Speed its running at 1600 and about 120F. This machine is more than adequate to run EMC on my small mill where a rapid of 15 IPM is sufficient, it certainly can't cut at that speed without serious enhancements to both spindle power and coolant & rigidity. I have had it up to 37 ipm but its not at all reliable over the whole tables range, the gibs are way too short and it binds at the ends a bit. The bare minimum to run EMC is probably a pci based machine & a 400mhz cpu. But those machines are yard sale stuff around here, with a decent monitor costing 2-4x what the machine can be purchased for. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
