I have the service manual, but it only includes the power supply and
CRT schematics, none of the logic. The only schematic I've seen was
reverse-engineered from a 9100B, very cryptic, and I have a couple of
9100A's.

The HP archivist claims that she has all the schematics and, no, we
can't see them.

These aren't museum pieces to me. These are very cool but broken
calculators I want to fix and use. There has *never* been a calculator
that is as nice to use as a 9100.
