The DIN-8 connectors can be used for straight serial, as to a modem,
or for AppleTalk - you can have both on one machine at the same time.
Both serial ports have the same physical layer driver chips, and they
are just the A and B channels of a Z8530 - interchangable.

I doubt it's a serial connection - most likely it's for driving an
external mono monitor.
Crack the case and look at the expansion card to be sure. Radius and
others made video boards for the Mac.
