This sounds good. How many hours have you had it running without trouble?
Which version of EMC are you running? Does TkEMC work, too, or does it
freeze up?

Why does this cause a problem. On my system, if the servo amps don't power
up, then I will get a following error message as soon as I try to move more
than
the following error limit, but that doesn't cause the computer to be unstable.

Well, if the P200 doesn't work, and the K6/300 is demonstrated to be totally
flawless, you should document as much as possible about the two machines.
I would like to know what motherboard, motherboard chipset, CPU type,
amount of memory, video card (or video on MB), what servo or stepper
interface, and the .ini file for all combinations of machine that work well,
or don't work. Also, the Linux brand and kernel version (like 2.0.36), the
RT patch version (like 0.9J) and the EMC varsion (as 20-Dec-1999) will be
needed. I will volunteer to build a database of these results to see if this
is any help in tracking down the trouble we have been having. All EMC users
are urged to contribute!
