2M VME 3/75

 Two megabytes of memory and connectors for the piggyback SCSI board 501-1045.

 With the component side up and the VME connectors away from you, the D50 SCSI
  connector is in the near right corner, and the piggyback connectors are in
  the center and left middle.  The memory is in the far right quadrant.

 Jumper J3101 at the left far edge should be jumped, and J3102 just nearer
  should be unjumped.

 There are two eight-position DIP switches, each of which should have only one
  switch on, and all the rest off.  Switch 1 is to the left.  For this board,
  both should be set identically.

 U3118 and U3119
