Hi! The board looks a lot like the Vector Graphic designs. I wonder if they are related somehow? VG uses those particular light blue shrouded right angle dual row header connectors. Also the PCB layout seems very familiar although I do not recognize the board. You might post something on the Vector Graphic mailing list and see if there is some more background information any of the former employees can recall.

VG operated in the Huntington Beach CA region too IIRC. That is where my VG clone (NNC) came from as well so it may be some sort of board released after the VG collapse or from a supplier.

Thanks and have a nice day!
