Hi:
better luck looking for specs on that drive. AFAIK it
is identical to
the RD54 except for the label DEC puts on it.
There's also a jumper that has to be added to a stock Micropolis drive to
make it into an RD54. This is R6 on the main drive printed circuit
board. Solder a wire in where R6 is indicated on the board.
