I've managed to get an ECS (OK KS 2.04 + ECS Denise...not sure about Agnus memory limit on this machine) Rev 6.2 machine up and running.
Now usually colour codes mean certain things preventing boot like bad chip ram etc but couldn't find any useful info about what it means if the screen just remains white and the insert disk anim for KS2 or hand holding disk image for KS1.? means. One site hinted at a bad KS ROM but I don't have any spare right now and only an A1000 and A600/A1200 which is no good to test this ROM from an A2000.
Any ideas?
i suggest you buy my Amiga 4000.
