OK, let us know when you have gone through those checks.

Just to clarify, the situation you are now starting from is, what...

-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?
