Well, not from DEC. I did have a Pertec T9000 (same as
TU45) on my uVAX system, using an MDB MLSI-TM11 controller.
It emulated the DEC TM11, which was never available in a
Q-bus version. However, even with my limited VMS driver
skills, I was pretty easily able to get the TM11 driver
converted to work on Q-bus.
I also figured out how to set up a system so the
non-volatile config memory could be accessed via the uVAX
I do have source and .exe of that driver, but it is for a
VMS 4.7 system.
