On the older babyVAXen like the VAXserver 3100 this connector was an
MFM interface to connect external MFM drives. On newer MicroVAXen there
are two of these connectors with a QBus interface on them. I never saw
a babyVAX with build in Pertec interface and the connectors for SCSI
where HD SubD 68 or normal Centronics 50 pin. Serial multiplexers used
36 (?) pin Centronics connectors. 
I don't know what the connectors on the biger machines may be used for.
