(talking about Tony Duell's circuit diagrams)
After examining the results of his work, I would
suggest that your
friend should learn how to CORRECTLY scan hand-drawn line art.
I will not make the mistake of buying later versions of his disc
What's wrong with them? Do you object to them being hand drawn?
I have used the 9915A and 9825A schematics when repairing my 9915B and
my 9825A (ongoing), and they are clear, correct, and readable [1].
Look, Tony is doing a service to the community, *and* he is not making
money out of this, so bitching about his insistence on doing things his
way is counter productive both for you and for the rest of us.
Personally, I would like to thank Tony for his efforts and contributions
to this forum.

[1] in fact the 9915 schematics are much more readable than the HP
supplied diagrams for the HP-85 (which has many similarities to the
9915). In fact any time there was disagreement between the HP prints
and Tony's, the hardware agreed with Tony's drawings.
