I gott an M8549 Universal Substitute Board off the 'bay recently,
but it's not what I was expecting, which was a blank board with
lots of places to mount DIPs.
The board does have 27 pads for 16-pin DIPS, but also three
"DEC10101" and one "DEC10110" chips on it (are those ECL?), many
traces on the lower half of the board coming from the Omnibus
fingers, and a couple of dozen 0-ohm jumpers.
Is there a schematic anywhere? I can't find it on bitsavers... So
what exactly did I buy??
