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 -tony
