You did those schematics? I'm impressed.
It's been quite some time sinc=
e=20
I've been quite that ambitious... :-)
Err, no. My cat drew them, and I simply plagarised them :-)
More seriously, yes, I've traced out the 9816 scehmatics. And many other
machines. The larger stuff is on the hpmusuem.net website, you can also
get a CD-ROM of everything from HPCC.
The 9816 was by no means the most complicated machine either (there were
a lot of helpful clues too : the DIO slot pinout was known, that gave a
lot of the signals on the CPU boartd DIN41612 connector, for example). If
you want a raal challenge, try an HP9100... Or even an HP9845
