QBUS boards...

I've got some QBUS boards that I'm trying to identify and place a value on. 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. 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. 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. 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. Any input on this will be greatly appriciated! g. -- "I'm not crazy, I'm plausibly off-nominal!" Proud owner of 80-0007 http://www.f15sim.com - The only one of its kind.
