I recently obtained a DLV11 clone manufactured by 'MDB systems inc' on Ebay. It appears to have some solder style jumper points and a 10 position dip switch. Anyone have a spec sheet or know of this card, I'm not finding anything useful with my google search.
Thanks

RSX11M+ requested an image, put one of the qbus board in question, and another of a unibus
board I found I also own up for those that are interested. Sorry about the glare from the flash, I don't have a very elegant camera setup.

I have a fair amount of MDB information here, which I gotta dig to get at. Unfortunately , if I recall - almost all of it will be UNIBUS.

Can you post photos anyway?

I looked on ebay for a photo but didn't find any.

I think that the SMU is system monitoring unit, we used to use them in a Q bus MDB backplane as the terminator and one of the two connectors is a source for real time clock.

And the other connector goes to the front panel boot/run switches and lamps.
