Early Riser P/N 27F4625

This riser is bare of anything to the right of the MCA slots but the battery/speaker connector.

Newer Riser  P/N 27F4625

This riser has an addition of a resistor, a 74F08N, and a bit of wiring on the back.

Late Riser P/N 27F4666

  This bad boy moves the battery/speaker header down and adds a few resistors and capacitors.
