Here's the pinout for A1-J6 & A1-J7 from Joker Poker. I would imagine it's standard across System 1 games.

I just checked the schematic for Countdown and the colours are different to those I posted from JP (why they changed I don't know!). Do you have the schematic - pretty easy to figure out the colours.

Could you post some pics of the front and back of PCB showing the replaced IC's and connector pads?

Please post a closeup of the lower left corner where the chips were replaced.

Check the following connector pins are OK:

Left Flipper switch
A6J1-9 > A6P1-9
A6J1-10 > A6P1-10

A6P5-2 > A6J5-2
A6P5-4 > A6J5-4
