First up is a Parallax graphics board with the number
990-0001 on it.
It's got a small cab kit with four BNC connectors on it marked RGB and
Sync. There's a 75Ohm terminating resistor on the Sync connector.
It looks like Parallax produced at least a few different QBUS framebuffer
boards.
Next is a board made by MDB Systems that has
"MLSI-DR11-W" printed on
it. It's got a cab kit with it that has two 37 pin(?) d shell
connectors on it.
It's probably the MDB QBUS equivalent of a DEC DR11-W, which is a
"General purpose DMA parallel interface".
I've got a cab kit for a PDP-11 of some kind (I
_think_). It's got
two 25 pin d-shell connectors on it marked "A0 (Console)" and A1.
Each has a rotary knob underneath for setting a baud rate.
This sounds like the cab kit for an 11/23+, or possibly an 11/53.
A D315 distribution panel. Has four 25 pin d-shell
connectors on it.
A three board set joined with short IDC cables consisting of one M7169
and two M7168 modules.
That's a VCB02 framebuffer card for a QBUS VaxStation.
Nothing looks particularly valuable from the list. I'd say $5-10 per
item would be a fair value, unless you find someone who has a real need
for one of them.
