Stratus and 220V

do you mean 68010's they had systems with 68K's and
also with 88100's (almost the death of them, they believed
Motorola's BS about the 88k)

The periperherals they used were 110, so should switch. I don't
recall whether the actual PS modules were or not.

A lot of these machines had to be made 220 because UL got a wild
hair up it's butt that you couldn't run 30 amps of 110 thru a metal
bulkhead safely, so to run these cabinets, each bay needed 220 / 20 A

but the insides were frequently designed before the 220 requirement, so
you get some wild wiring on the AC of some boxes. I know that there
were a lot of Honeywell Level 6's that had 220 on the back but were
all 110 inside.

Note: the cumulative power was 30+ amp at 110, but if you could have
run 3 extension cords to one bay (also a no no) there would have been
no problem. So you had to run 220 thru the bulkhead and break it
up.

This only applies to 220 2 phase type power, not 208 3 phase, which is
different. Most of those systems have no 110 in them at all.
