The DEC ones
can sometimes be converted to RX02s. I think the older (RX01 only) were the
M7726 and M7727.
The newer RX02 boards, M7744 and M7745, can be used for either.
DISCLAIMER!! I'm taking
the board numbers off the top of my head. They could be wrong.
I think the boards are very different and thus easily distinguished :
The RX02 boards (which can be set to RX01 mode with a DIP switch on
the controller board) :
Are interconnected by a 20 way cable ending in Berg connectors
The controller board has a pair of 2901s (40 pin chips) and a 2 position
DIP switch on it.
The RX01 boards :
Are interconnected by a 16 way cable with DIL headers
The controller board has no 40 pin ICs, no DIP switch. But it has
a 36 way DEC-style edge connector for a KM11 board
