I got my Microvax 3300 today...  powered it up, ran fine for a little while then
I noticed a little waft of smoke coming from the power supply, I shut it down
and when I powered it back up a few minutes later the power LED on the power
supply didn't turn on but the fans kicked in.  

Now the processor module comes up with an F that stays there on the LED display.
 The switch for ethernet media works (the lights change when I flip it.  I'm
pretty sure the power supply is probably toast.  If a power supply in a VAX
takes a $hit will it take out the backplane or the cards or will replacing the
power supply take care of it?

What does the F mean on a KA640 anyway?

I'm pretty bummed.
