I think we got the 3rd 360/50 produced. It wouldn't come up and they escalated 
up the chain all the way to Armonk. Some gruff old 'specialist'-with stogie was 
flown in. We had a couple of storage oscilloscopes and his basic diagnosis was 
that it hadn't been 'timed'. So he set about to sync the clock cycles and about 
half way thru an SE says "I found the bug!"(Similar to Grace Hopper's moth). 
Big ol cockroach crawled across the side panel. Both were escorted from the 
room.

I think the 2955 FE/DAU (Field Engineering / Data Access Unit) was

around for the very tail end of the S/360 era.
