Board has 3 notches. on back it says "DEC DMV11 Microprogram Control". It
also has the following numbers: M8053 on one of the top fingers. Also
CS*ABCDEFHJKLMNPRS also DDCMP ADDR BOOT enable. Can anyone tell me what this
is and what it does?

I believe this was most often used as an IO Processor for Sync
communications... The DMC and line card used to handle DECnet as well as
other protocols at 56k sync speeds -- the DMV is a QBus version...

Bill is correct, is a synchronous serial network interface. DDCMP is a
DECnet protocol and allows the device to be MOP booted over DECNET if
you've got the ROM for it. I've got a couple of these (plus some with S-box
handles) and would love to get the technical specs on them. Then I could
hook them up to a CSU/DSU and run Frame relay lines around my house :-)
