We were having a ufiche party for the 360/50 and the lead systems guys got an 'emergency call' from a former student at one of the local mills. They had a 3500 and had run the payroll three times and different results every time. The ironworkers were milling around in the parking lot with evil intentions. Did we have a 'storage oscilloscope'? Well we rounded up a couple and headed for the mill. Long story short they had expanded, but had the new wing of 50 HP Bessemer converters on the same power feed as the computer room. Every time one of those big motors kicked in they would get about a 140 volt spike on the 3500 bus. The memory would actually change state. Isolation transformer fixed 'em right up.
