 Here, the front of my power supply reads:

 SPECTRAVIDEO
 POWER SUPPLY
 MODEL NO: 318 - 202
 EXPANDER SV-601 USE ONLY

 INPUT: 120VAC 60 Hz 65W max
 OUTPUT: PINS 1,2 14V 2A
              3,4  6V 3A

 The output plug is labeled thusly:

           -----------
     1 -> | *       * | <- 2
     3 -> |   *   *   | <- 4
           -----------

 I would guess, with outputs rated at 6 and 14 volts, that this is an
 unregulated supply. 
That's an excellent starting point; 6 & 14 volts is ringing bells with me,
and there are some caps on the motherboard which could be part of a
regulating circuit. Pinouts match too, I think. I can make sure tonight.

Thanks!
