just scored myself a complete Apple IIe system.
It's an 83 model,
even though it's numbered 82,
as they didn't make them then,
so the Aussie early boards have the wrong date as I've found out on the web,
as they were all made in 83, with this wrong date.
Anyway back to the question.
I got an original mono chrome monitor which I'm not using, and I found a proper color screen, which are hard to find now days Down under. But when I booted it up all is working fine the controls all work, but the colors are wrong. I've tested a few different games, to see if it was one of them, and hooked up a little LCD TV to the apple itself, and the colors are fine. But as soon as I put it back with the apple monitor colors are wrong again.
I know this monitor has been in storage for maybe 20 years and the guy I bought it off tested it in January and reckoned all was working, and I be leave him as every thing works the brightness is fine the tint and the other controls work fine. but the colors are wrong.
I've also tried the switch on the mother board which is only found on Pal boards. And when its on mono I get color but wrong colors. then I switch the mother board switch to color and it comes out black and white. put the tv in and its round the other way with colors working fine.
To give you guys an Idea,
one game is Karateka.
Where the blue is supposed to be in the intro and the 1st level its red instead. and where the orange is meant to be, is green. but all the controls adjust and work like they would if the colors were right.
same thing with Zaxxon.
Where its blue, its red, and where its red its green.
hopefully I can get this working as the colors are quite annoying. and ugly.
I'm guessing its some battery or capacitor on the main board inside the monitor its self come loose, or old and failing.
but I don't know much about repairing these old monitors. so any help is appreciated. :~
