My memory for most of the larger VAXen is that they
balanced power
supplies across the phases, and *might* have used 3-phase blower
motors in the biggest boxes (8800 for example).? Definitely check
wiring, but the 6000 series may well have single-phase blowers.
Should be good there. They are at least single phase and might even be DC.
When we got an 8530 at work in the early 90s (needed a
machine with a
Nautilus bus for specific hardware testing), it was definitely a
3-phase machine and since we were in an industrial setting, I just
tapped into our panel at the back of the warehouse and wired up a
3-phase outlet for it.? It never sat on our datacenter floor as a
result, but it really only ever had one purpose and that wasn't a
daily driver.? Too much power, too much heat for so few employees (at
that stage of the company).
I'm sure its going to be a pretty good heater this
winter in my small shop.Running solo should not be too bad. Less than 5A I remember
reading somewhere.Of course if I keep adding processor modules and/or an RA92 or two I can
see that changing.If I can leave it running I'll add it to my other Hecnet
machines(emulated)
