   You can find a couple of scans I did at:

                  www.chebucto.ca/~ab616/dsc-ic.gif
                  www.chebucto.ca/~ab616/dsc-rgb.tif

   They came out a little dark but turning up the screen brightness helped
with viewing.

   There is a DAC OUT/SPK OUT phono jack selectable with a jumper and an
AUX. OUT phono jack.

   The writing on it is: MMI DAC BOARD 1982 Temporal Acuity Products Inc.

   The gold chip has AD558JD 8244 written on it.  The other log chip has
LM3900N RAYC8236 on it and the short chip has P231 LM 386N-1 on it.

  There is a slide volume(?) control at the back of the card.
