No Sellam, no one took the time to reverse engineer TSB....
This manual is called 2000E IMS (Internals Maintenance Specification). It
was written by HP, and I'm pretty certain it was used to train new
programmers who were to work on the TSB code itself. It's just way too
detailed (and most of it printed too nicely) to be someone just doing some
reverse engineering.
I'll probably get to scanning a few parts of it in next week.
Cheers!
