Who knew that using a meter for hours and hours could be so much fun.
Nothing jumping out at me yet, but I'm not finished (bearing in mind how many chips were replaced on here, there's a lot of socketed chips to be tested).
To answer your questions:
1. Random characters as post 92 with the original 6502 in place.
2. Same with Slothie EPROM in UD9
3. Same with Daver2 EPROM in UD8 and original UD9 in UD9 position
4. ROM/RAM board in place with a different 6502 - I get the attached screen with BASIC 4.0 selected, ROM and RAM replaced with those on the ROM/RAM board and no keyboard function.

-Random characters on screen no matter whether you start the machine with...
Slothie EPROM in UD9
Daver2 EPROM in UD8 and original UD9 in UD9 position
Ram / ROM gizmo in place
No matter which of these options you try the switch on state is the same, just random characters on the screen?
