Is this a 200/DL (RS423 data lines only) board?

A normal 200 would have two large IDC connectors on the pcb for
serial I/O
The DECserver 200/MC had 8 DB25 connectors on the back, one for each
RS232 connection. These connections had full modem control.
The DECserver 200/DL had one 36-pin connector that broke out to 8 MMJ
connections. Only the data leads were present (no modem control).
I don't know how the motherboards differed between the two models. I
wouldn't be surprised if the MC variant had 8 connections to the
motherboard.
I'm surprised the 200/DL didn't just put 8 MMJ connectors on the back
of the box ... would have saved space and been less of a hassle thirty
years later for people trying to run them!
I don't have any service information (that I know of) for the DS200
unfortunately.
