Hi. I seem to find this connector with 50 pins in three rows in a D-shell
on my VAXservers and VAXstations. I even have one or two on my DECsystem
5840. Could someone tell me what they are? Three rows. 17 - 16 - 17.
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.
