My memory is very very very fuzzy on this. I seem to recall that microcode

That's all that I remember about it as that's not the part of things that I
was working on, just heard grumbles from other folks about it.

The 32032 made sense for the workstation division
based on the data sheets.
But, it turned out to be extremely buggy, and unlike the 68K I don't recall
the ability to look at and patch the state of the microcode.
Did you have the ability to look at and patch the state of 68000
microcode? How?
