I see a big problem with this flowchart, the path on
the far right does
not exist, please delete it and then the flowchart will be
believable.
..
I do think there are not nearly enough arrows pointing
upwards
LOL Rob, Mark.
Today it's all going to come together and hopefully
the outcome will be a
fully working PET4032 and an extra diagnostic tool to add to the
collection.
Of course we all know something ELSE unexpected will
happen.
Yes, I love the case design of the PET. It looks just so retro and '80s
futuristic if you get my meaning...
I designed that tounge-in-cheek flowchart as a kind of catharsis having
just spent the last three weeks, firstly fixing my Apple II+ which was a
non-starter on checking (a faulty F8 ROM in that case) then followed by the
next unit I tested, whose 74LS500 in the video circuit failed after about 5
mins. I'm almost afraid to turn on any more...but then...Schrodinger's cat
and all that. I need to know!
