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?? -Charles
