I was looking for a way to sore my cartridges and couldn't find anything suitable so I designed a tray that can be wall hung stacked or laid flat. I drew it up in Sketchup and printed some off with a 3D printer.

Excellent. I changed chip RO-3-9502-001 and now everything works as it should. Thanks for the help everyone.

I've since tried Q-bert and Soccer which both worked yesterday but not today. Both don't go past the startup screen. Do you know which chip is the EXEC ROM as I might have one to try?

Hi All. My first post here. I had a non working original PAL Intellivision that I've managed to get working but only with non Mattel games. Demon Attack, Donkey Kong and Frogger work perfectly but Mattel games won't get past the copyright screen. I have some spare parts I can swap around and am guessing it's a faulty chip but does anyone have an idea which one. Any help will be much appreciated. Cheers John
