Before somebody jumps down my throat and teeters on my wishbone, it really
isn't all that "rare". I just checked and found a copy at:

As you probably know, the console is controlled
by an 8008
microprocessor. Of course it's an 8 bit device. Maybe some 'carry' is not
working correctly.
Alas DEC didn't publish a source listing (or even a binary dump) of the
console firmware in the printset. This is going to make troubleshooting a
little harder, since you probably don't know what it should be doing. It
is clearly running a program, and that program is reading the keyboard
and scanning the display. So it is somewhat correct.
DEC did publish it in a "rare" version of the KY11 Maintenance Manual. It
contains the complete 8008 listing.
I put a copy at my website - available by anonymous ftp to bickleywest.com
in the "dec" directory.
