Unidentified Quad-Height Board:
  System Industries
  9901-6082-a
  Date Code 621

 stencilled on the back -- 61907 113

  It has 2 40-pin connectors, 2 8-switch DIP banks and 1 4-switch bank,
and 4 AMD 18-pin chips - AM2905PC / 8335DKP
  Lots and lots of 20-pin doohickeys - AM2908PC / 8512DMP
  And some Motorola 20-pin thingies - SN4LS244N / I8709BD
  Socketed 28-pin EPROMs, I think, with label attached:
  9900-8954
  9900-8955
  9900-8956
  Socketted smaller 20-pin ICs with labels:
  9900-8953
  9900-8957
  9900-8958
  9900-8959
  9900-8960
  9900-8961
  9900-8962
  9900-8963
  9900-8964
  9900-8965
  9900-8967
  9900-8968
  9900-8969
  9900-8970
  9900-8971A
  9900-8972A
  9900-8970

  There are other components, but maybe that's enough.

  I can't find any reference at all online. Does anyone have a clue?
