ta for the offer - I neglected to mention that I actually *have* a
Dragon 32 too, again which I'd never found the time to test!

After getting frustrated with the '64 I tried it, and it runs - but
starts with a green background and startup text in the top-left, which
seems to be different to what the '64 is trying to do...

Now, the only 18 pin IC on the '32 is an LM1889, which apparently is
some sort of TV modulator IC. If that's what's missing on this D64 it
might explain my dodgy video output :-) (although without it I'm pretty
surprised I'm seeing anything remotely stable on the display; possibly
the machine has some other fault too)

If someone can confirm that my missing chip *is* an LM1889 then I can
desolder the one from the '32 and try it in the '64...

cheers

Jules
