I have scanned the manuals that came with my Ford-Higgins Powerframe machine. It is a QBUS PDP-11/73 machine in what looks a whole lot like a DEC BA23 enclosure. Not sure if it's a clone or a licensed rebadge. The CPU board is DEC, the memory is a Clearpoint P/N 3325/300 (size unknown) and the disk controller is a Dilog DQ215 P/N 33214701 (SMD?). It has a combo fixed-disk/cart drive that their docs call an RC40. That looks like a DEC part # but doesn't seem to be anything they made. There's very little out there about them (I found a 1992 Usenet post these docs online. http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/FordHiggins And some photos: https://goo.gl/photos/DiXaiiMKXNorGqzVA The machine has been given to a friend in search of a QBUS project, so I don't have any more pics at the moment. -j
