Amiga 1000 Green and Black screen only
Hi,
My Amiga 1000 gives a green screen and than it turns black, and again green and so on. connected only power and video out. don't have a keyboard. Also disconnected the front ram pack. Faulty ram chip? what do you think? type of ram chip is MN41464-12. I have some NEC D41464C-10, should these work? thanks |

I checked A1000 boot rom for color codes: green is (unsurprisingly) RAM error. RAM check from address 000000 to 3FFFF failed.
Most likely reason is connection problem anywhere between CPU and RAM chips (buffers, Agnus etc). |
