> Do you mean the seven segment displays on the paper tape reader?

That's correct. There are seven 7-segment displays on the front, with 6
grouped together. It should make for a nice clock. :) You can even add a
Sonalert to the output for an alarm, and have a 7-day calendar stored with
alarms updated with paper tape! Okay...I surely don't have that much free

So if you jam the PROMs output to 7777 for any address, you can get to

Or you can just remove the PROMs altogether. There's sockets for a total of
2k of PROM. Only 512 bytes are populated in these, though.

I asked Al a while back, and he seemed to indicate that everything you gave
him is up on bitsavers already, which appears to just be the manual. If
there is more information out there, that would surely help us.
