a M857 board with a RS232 cable on it and BC01R-25 on
it.
Anyone know what an M857 is? I guess it might be a DF11 async answer mode? I
found this:
https://www.computerhistory.org/collections/catalog/102731577
but I think the number there is wrong; I'm not sure exactly which KL10 board
is an 'MBOX Control 3' - it might be the M9537.

Sounds like it was a generic cable that probably
worked with several
devices.
Yeah, the BC01-R was used with an M957/M970 header card (not sure what the
difference between them is) in the DF11:

Not sure where else.

No, it's a single width full height M series board from the early
1970's. As mentioned it was probably from a DP11 or some other RS232
sync serial device.
