Has anyone ever had this message pop up on your screen in about
20 point high letters.  After which you must hard reboot?

dit dit dit dahhh:

	PARITY CHECK 1

What does this mysterious message mean, these crashes seem to happen
randomly, but I'm sure there related to something we can fix.
The grubby details:

	1) PC with Enhanced color, 8087, 256Kb.
	2) Kinetic Systems Camac interface card (2925)
	3) 50 wire cable to the camac crate controler (also Kinetic)

We are trying to narrow this thing down, it could possably be the 
2925 card, but it seems unlikely as in operation it works beautifully.
However when I run the diagnostics provided with the pc, and enter
0 for run diagnostics, the disk just spins and spins, but if I take the
card out, Hunky Dory, any ideas?

I thougth that the location was bad and we were getting rf interference,
but that does not seem to be it.  Could glitches comming through the
cable cause this kind of crash?

I realize that this probably isnt enough to go on to really solve the 
question, but I would even be gratefull for a partial list of things
that cause that parity check message.  I can not find it anywhere in my
documentation (I dont have the Tech Ref manual yet).

Please respond by mail.
