Dear cognoscenti, I am putting together an old DEC 11/53 system, and so far am missing the SLU for connecting a console terminal to the processor card. The card has a 34-pin flat cable connector, but my (MicroVAX vintage) SLU has two cables (10-pin and 20-pin). The SLU sets baud rate and makes up the serial connections, that's about all, so with sufficient information I may be able to just cable up directly without an SLU. Can you suggest a source for pinout information for the subject processor/SLU interconnection? Thanks for your help. Tom Roach
