DRAM 128K system has stopped working

[CheshireNoir]

Thanks Ernest and someone.
I'll try holding down G on Thursday when I have some time to work on it. (Tonight was silly videogames and tomorrow I'm going to hang out at the local Maker's space)

someone, are you suspecting CHARRAM may be the issue? The system isn't booting to any of those strings by default. I get a "no video synch" state. They only appear after I press RESET. Once they appear, the system doesn't do any more and the graphics seem to flicker like crazy.

Hopefully on Thursday I'll also have that capacitor I need.

Cheers and thanks for everyone helping here. BTW, this is the same power supply as before. I understand the 'bee can be sensitive to power supply changes?
