Subject: RE: HP 9830A always turns on with blank display
What I don't get, the compleet 9830 is on the HPCC DVD, and that's not the
DVD from the HP calculator museum.
But you also can download all the diagrams form the hp computer museum site,
www.hpmuseum.net.
What's also very helpful was for my, when I was (with the help and advice
from Tony) fixing my HP 9830, were the HP patents from Eric's site
http://www.brouhaha.com/~eric/hpcalc/patents/
The patents tells you a lot about how the machine works and how the firmware
and routines are build and what they do.

Thanks for those links, Rik.? The hpmuseum.net site is a tremendous resource, along
with the others you mentioned
