Summary: It's a dual width qbus board with 1 DLV11-J port, 32KW Boot room, on board LTC circuit and has a 16 pin connector to attach to a front panel. I dumped the prom's and you can see them over on the VCF Forum/DEC page. I used PDP11GUI to probe the I/O space and it looks similar to a MXV11-B boot board, with the addition of a serial port, LTC and front panel control. The board has copyright 1986 so it's not that old. I guess a front panel would have; LED for RUN, LED for DC OK, a switch for HALT, switch for RESTART and possibly a switch to disable LTC. The board has a couple of 4N25 optocouplers and what signals would need isolation?

Yes, I would like to use this put together a working qbus PDP11 using either 11/23 or 11/73 CPU, just for fun. Doug
