I'm trying to restore an original Mac 128K and am having an issue. It started with sad mac telling me to replace a RAM chip. In the process of removing the old chip and putting in a socket, the video output went from normal sad mac screen to this:
Normally, that would look like an analog board problem, but I plugged in a Mac Plus board and the display worked perfectly, so I'm sure its not the analog board. I don't think it's my memory chip as I get this screen whether the new memory chip is in or not.
Anyone seen anything like this before or have any ideas?
