Some years ago (~10) my Macintosh Classic II working Ok, but now when power on - "standart" chekboard, no surprises.
Computer board now is recaped, but is still checkboard on screen.
When in my Classic connecting logic board from other Mac Classic - all fine, boot up and working.
All voltages be Ok, so, i don't understand what happened and where is problem. My only idea is that it should check RAM and ROM chips, but I don't know what they are and why I can't read them with programmator.
