Default Re: Commodore PET 2001 voltage regulators

Hi,

Thanks for all the replies/thoughts, and apologies for my late update on these.

Just from some of the replies, I've included the original screen shot of when I first aquired the PET. It was from this that I replaced the video RAM which (briefly) showed the Commodore BASIC screen. After switching the PET off, then back on, this is where I am now.

It did briefly kick into life (with the garbled screen picture I posted), but since them the screen has been blank.

I'll start to go through the other replies, and some more tests that have been carried out.

Regarding soldering, I'm happy to do this. I have worked previously on other 8-bit machines, and have soldered/desoldered. This is the first time I've ever had the chance to look over a PET.

Right, I'll update with the rest of the findings!

Thanks,
Tim.
