Re: Where's that color signal hiding?



Are you sure the monitor has PAL support? It's automatic or manual selectable?

Anyway, the Apple II's video generator is so tightly tied to NTSC, that here at Brazil some Apple II clones owners opted to "revert" the localized video generator to the NTSC standard (every single TV or Monitor has NTSC support around here nowadays).

You can see some details here (sorry, page in Portuguese - I hope Google Translator can help you):

Please check and recheck everything to be sure that the circuits are similar before attempting any modification (but odds are that they are : I had managed to put my dirty claws on some foreign Apple II's , and they rarely diverged at all).

I have some european Apples that I used to run with those little b/w
9" or 12" monitors. Now I was given a small Sony Color portable video
motitor with BNC 75 ohm inputs on the back and I wondered if I could
use it to finally play Apple Galaxian in full color ;-)
Unfortunate I got only black and white pictures on the screen so far.
I do have cable to connect the Apple video connector to BNC and a
variety of untested PAL cards for slot 7. Playing with these I did't
get better results though. A third party PAL card has a TV encoder box
onboard and two video connectors, one says Video OP the other UHF
which is for the TV probably (and there is no channel swiching
possibility on the small Sony monotor). The original Apple PAL card
only has one video connector but this reads Video input (?should this
be used with a Sup#r#Mod then?).
Can anybody help me how to set this up, or tell me where I should find
the color signal in theory?
Furthermore does anybody know if the earlier Apple II mainboards (the
rev1 type with the memory blocks) work with the PAL encoder in slot
seven as well? They do thve the X O solder type jumpers as far as I
can see.
