Wow! I thought the CQBIC was not populated on the KA50.

Hmm. I do not suppose that this identity flag can be permanently stored
anywhere other than in the firmware flash ROM. I'm sure DEC wouldn't want
people to suddenly discover that their machine shape-shifts when the NVRAM
battery is disconnected. So does this console test actually erase and reprogram
a sector in the firmware flash ROM, or is the change only in effect until the
next power cycle?
