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

Well, there was a time when I might have given something like that a good
shot, but not any time recently...
On top of everything else my eyes aren't what they used to be. :-(
