Hello!

Looking at photographs on the web I notice that the 3/50 and
3/60 have a single DIN 41612 style connector on the right
hand side (components up, outside panel towards you).  Is
this VME, something proprietary, or just an interesting way
of getting power onto the board?  ;-)

Also, I noticed that many SUN 3 boards are 9U, with three
DIN 41612 style connectors (at least, that's what I'm
assuming they are).  I'm guessing that two of these provide
a 32-bit VME bus.  What's the third for?

Regards,
  - Andy.
