Now need to figure out what backplane this is. From what I've seen on Ebay from the same seller, this may be a small LSI 11/03 system backplane, since a cpu card + memory card is now listed for sale. Hopefully can snag that and have a nice little system with what I've got.
This is a backplane for what appears to be an H9270 PDP 11/03 system.
See page 136 of this manual
