Like I said, the original TED prototypes must pre-date this by several months so the keyboard 6529 must already have been part of the core architecture. I have a pre-production C16 board which is earlier than this one (based on the date codes) and that has the 6529. > > One thing to check with the TED you got is the noise generator.

I don't know whether it's my imagination but some of the games & demos appear to have wrong colours though. I will compare to some 8360's and see if there is a difference. I have other 7360R7's to compare with. > > Is the ceramic PLA dead? Is it also a 251641-02? No, it works fine and yes it's a 25164-02. I'd swapped out some of the chips when it first failed to boot and I never put it back for these videos. > > I notice that there are a lot of similiar sounding words that could > have been left out and made space for other words.

I just noticed that this is a 7501R1 (0184) whereas my early C16 has a 7501 (5283) I wonder if they're different?
