At http://www.hpmuseum.net/display_item.php?hw=171 at the documentation
section you find the diagrams made by Tony.
For the crowbar I use a zener SCR/Thyristor construction, I didn't made one
for the negative voltages.

Wow, amazing. Those schematics are quite a piece of work, Tony! Did you
service these machines professionally, or was that a labor of love, or both?
I had seen the site, but didn't notice the buttons for documentation at the
bottom! By the way, thanks to Rik and Tony for your very helpful pointers and
responses.
With this info, I should be able to rig up a ROM cartrige, in case I'm able to
get my hands on images of the Matrix, Disk, and Network Analyzer control images.
Best regards,
Dave
