Johnny;
I would be interested in hearing more about this (or any) 11/60 microcode
bug :->! And how the OS (which?) worked around it.

There is a weird microcode bug in the 11/60 CPU, which force the OS do so
some silly things in general, in order to run correctly one that one CPU.
Things that are just wasting a few cycles on all other CPUs. I bet DEC had
fun figuring that one out...
(I don't remember the exact details now, but I could go in and read the code
to find out again, if needed, unless someone else remember the
specifics.)
