OK, got Rocky + Bullwinkle back online again. There is a loose connector SOMEWHERE on the CPU board that I am going to have to rebuild, but by the time I got it going I stopped keeping track of which one I had reset. SO NEXT TIME, I will find it, flag it, and have that connector redone once and for all.
So 1.3 display and CPU ROMs are go! But ummm... I guess I can't tell the difference so far. I mean, YAY, I like seeing the 1.3 note at bootup, but so far, I don't notice much.
