Nice I don't have any such fancy peripherals, though I did get the controller board for a mass spectrometer from the scrapped unit o_O (No software, though.) Been having a lot of fun talking with the DEC guys over on the Vintage Computer Forum since I got it.
We just OEM'ed the thing from Xerox. They called it the 9700. In addition to running the printer, it had a 9 track tape drive, a disk pack, and a dumb terminal to control. It was fun to open up the interlocks and watch it run, especially in duplex.
