The circuit should work in PAL as-is. Connect pins 2, 5, 6, 7, 9, and 13 from the PAL TIA to the holes marked 2, 5, 7, 8, 9, and 13 on the board, respectively. Do not connect the holes marked 6 and 12. Then, omit R1, R2, R7, and C4.
Has anyone installed the mod in a PAL console using this method???
.....I have purchased some mods so when they arrive i will give it a go. Hopefully, if I don't blow-up my atari, I will post some installation pics to help others.
