The machine
has two scsi buses or ar least two SCSI connectors back,
one large and another of lightly minor size.
I cannot think of *any* MicroVAX or VAXstation that
has two SCSI connectors of *different* sizes.
It has two connectors of Centronics type. One is a
large Centronics type connector, over the three
MMJ connectors.
The other one is, seeing the CPU in its back, at
the LEFT, covered by one semiespheric cover.
This is a "short" Centronics connector.
I have the TK50 connected actually to the large
Centronics connector because is the same than
the manufactured with the TK50. But this don't work,
at least by now. I have no cable to connect the
TK50Z-GA to the short Centronics connector.
The central unit only put "Microvax 3100" in the front.
Is a desktop, not a tower.
Thanks and Greetings
