So this idiot just purchased an 9221 system from Tennessee (apparently
it was still in service two years ago, and is in wonderful condition),
and I made damn sure that the console with the IMPL tape was included.
I even tracked down the machine's former admin just to be sure. I am
going to tell him to guard that tape with his life.

The processor is either a model 191 or 421. How similar is the
microcode between other 9221 types? There are at least a few 9221s of
various models out in collections that currently have the processing
power of potted plants, simply because no one bothered to save the
microcode.
