I got a homebrew MT-11 driver for Unibus machines from somebody at work, and hacked it up to assemble for VMS 4.7 and adjust to the quirks of the MDB board (which were REALLY minor).

It is based on the stock DRV11-WA driver, with some additional logic to handle the handshakes between Jupiter and the DRV11. Additionally, I built a graphics library based on the NASA min-Vicar image processing suite, which was a hideous hack job that ran on the PDP-11. That used pre-assigned, numbered files. I generalized it to use normal VMS files of arbitrary size, but otherwise kept most of the original functions. I used the VMS table driven parser, tparse, to parse most of the commands.
