I have the documentation for the VAX-86x0 micromachines... And I have the hardware.
Want to do something? :-)

Because
everything about the KA730 microcode was "soft", it's fairly easy
to change the CPU microcode, update the console TU58 and reboot to change
the CPU behavior. I believe DEC even sold a set of microprogramming tools
for the 730, but I've never seen them and I don't know what's become of them
today.
Back in the day, I remember occasionally seeing docs on PDP-11 microcoding,
but I don't recall seeing anything for any model of VAX.
