@DmMacniel @Twig Yet not so sad: The A600 ECS chip is one of the few model that can handle 2Mb chip ram, so you can go up to 10Mb with 8Mb fast. Also it was the only version of the ECS chip with some features of AGA like "Blank Border" and I think 1280 super high res and VGA signals, the first ECS serie (A500+) can't do that. I personnaly need one if I want to expand my CDTV chip ram to 2Mb
