I've build several of these boards into Sparc 1 chassis.  This has
required a bit of modification but they do fit, and the SS1 p/s will work
with repinning.  A PC p/s will also work and may be easier to get up and
running.

Here are the pinouts, note that the power connector is identical to a
SS1/etc powersupply but the pinouts are unique (these are all for the 245
but should be the same for the 220).  The p/s connector is a "12-pin
mini-fit Jr. (I think that's right)" connector, available from Digi-Key or
similar sources for under a dollar. 

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

J1401:  Motherboard power connector.  Pin #1 is right next to the "J1401"
        silkscreening.  Note that this is the view of the connector on the
        motherboard from above.  Diagram:

Pins:
   1: +12 (yellow)
   2: NC
   3: -12 (white)
   4: GND (black)
   5: +5  (red)
   6: GND (black)
   7: +5  (red)
   8: GND (black)
   9: +5  (red)
  10: +5  (orange)
  11: NC
  12: +5  (blue)

I'm not sure of the precise use of the orange and blue lines.  One of
them is probably "power-ok".  Tie them both to the power-ok line of
your powersupply and you should have no problems.

J1404:  Floppy drive power/Case LED connector, 4-pin in-line.  Pins:
   1: Floppy +5V
   2: Floppy GND
   3: Case LED GND
   4: Case LED (+5V current-limited)

J1405:  Side fans/Speaker connector, 6 pin in-line.  Pin #1 is the closest
        pin to the SIMM slots.  Pins:
   1: Fan #1 (closest to CPU) GND
   2: Fan #1 +12V
   3: Speaker +
   4: Speaker -
   5: Fan #2 GND
   6: Fan #2 +12V

J1501:  Standard 50-pin SCSI connector

J1503:  Standard 34-pin floppy connector.  Manual eject PC floppies seem
        to work.
