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.
