Thanks; I have a spare power supply coming as well. I will start by swapping dc-dc converters first and if the problem persists swap the pdp power supply. I'll report back what I find.

One of our GSM1 machines occasionally stops running in the middle of a program and I haven't been able to figure out what is causing it. When the issue occurs, the "BM" (bus master) light on the SYS68K card drops out (turns off, no activity) the boa
