9100B Original HP Schematics & Flowcharts

[Mark]

You're absolutely right -not to mention the time spent by Tony to reconstruct these schematic diagrams !

Maybe I wasn't accurate enough (writing too early in the morning has its side effects) : I implicitly emphasized on the historic aspect of these documents, since so much ends into the trash can, only to be missed years later.

Besides that, it's clear that they don't cover everything, for example there's only the control section of the ROM. Could it be that somewhere, a reverse-engineering project is pending, including a dump of the main ROM ? That would open some doors to an emulator ! Dreams, dreams...
