Yes, it works fine.

Here you go, here's part of a file I typed up a while ago:

In the interest of helping people out who want to get these running,
here's a list of the pinouts on the board.  No warranty expressed or
implied, if you toast your board it's your own fault.  I place this into
the public domain if anyone wants to copy or redistribute it (a good place
might be an extended Sun h/w reference). 

The power connector is the same type as the SS1/1+/2.  If you don't have
a powersupply for one of them to hack the connector off of, Digi-Key has
the connectors for $0.84/ea in individual quantities.  It's the
"Mini-Fit, Jr. Series 12 pin Receptacle Housing".

Pinouts (these are the pinouts looking into the motherboard connector,
_not_ the powersupply connector!):

        connector on the motherboard from above.  Diagram:
