Hello, I am trying to restore a 128k Macintosh. The issue is that its logic board came with Macintosh Plus roms, and all I get is black vertical lines from the video. I understand 512k roms will work in the 128k, so I was wondering if Macintosh Plus roms will as well.

If they are supposed work without modification, it will indicate an issue I will have to resolve before I look into making replacement 128k roms.
