I am very interested in these drivers!
I am new to the group please let me know the proper procedure/process.
Thanks so much,

Hello, guys,
While rummaging through recovered backups from my MicroVAX I found a few
items that might be of interest to the group.
I got an MDB mag tape interface (quite possibly the ONLY Pertec Unformatted
controller ever made for Q-bus) that follows the MT-11 register format.
There was no driver for this. 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).
I also have a driver for my Jupiter 7 for the MicroVAX. Thus used a DRV11-WA
DMA interface with some wire-wrapped glue logic to adapt to the Jupiter's
50-pin interface bus. 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.
I also knew a fair bit about Versatec printers back then, if anybody ever
wants to get one of those hideous machines running.
If anybody is interested in these drivers, etc. let me know.
