Hi,

I think I haven't heard from Geoff of Oz for a while, are you still
around?

Came to think about Geoff because I have now blown two fuses of
VAX 6000's internal 110V power hookups (the main power box has
three what looks like standard 110V receptacles.) But not all
of them are equal, so it seems. The one that's not reachable from
the outside seems to be protected by a low-rated fuse. I suppose
now that this is where the backup battery is to be hooked up
an nothing else. I tried to drive an RA92 from there and it always
burned the fuse when the drive spins up.

I'm releaved now because initially I thought I might have destroyed
the drive (some inner short because of dust and dirt.) But it's
just that fuse.

Too bad that I can't power the second external receptacle. It's
this weird 3-phase conversion issue where you have to use the
phase that connects to this internal receptacle but not both of
those that connect to the two external receptacles.

How did you, Geoff, hook up both of your RA9x down in your VAX6400?

thanks,
-Gunther
