I have one of
these. The VAX Console interface is kind of interesting.
It is called the Real Time Interface, option PC3XX-AA, and includes two
RS-232 ports, a number of discrete I/O lines, and an IEEE-488 bus. The
VAX was attached to a 62-pin D-shell connector, according to a scan I
have http://www.chd.dyndns.org/pdp11/Pro380_RTI.pdf Looks like it would
have been perfect for use in a lab for driving test equipment.
That's why I want to play with one again - I have a variety of IEEE-488
devices, mostly C=, but a little HP and Tek.
I don't know what makes it a console. Presumably
some interface into
the VAX guts, but what that interface is I have no clue.
You really need the keyboard and display to make it
work. A terminal can
be connected to the printer port and used with ODT, but that is about
it, at least with P/OS, I am not sure about RT-11. The monochrome video
is NTSC, so a simple TV monitor will work. I had to dig out an old
TRS-80 Model I display to make it work.
Are VR201s really that hard to find? Certainly LK201s aren't.
