It was my understanding from using the 730 that there was limited

The Microcode was loaded was the "what made it a VAX stuff".
Well something has to load the ucode but whether that's a fixed part of
ucode itself or whether
it's a hardware state machine (or something) that feeds the loaded ucode
into the appropriate
RAM, I don't know. I've never delved that deeply into the relevant FMP sets.
