Looking the PSU, I'd tend to agree - there doesn't seem to be an
"input" wire anywhere.

Does it also prevent the hard disk and fan from starting? These
certainly don't do anything on this LC.

Well, none of those made any difference.

I think I'll go back to assuming that the PSU was dead when I was
first given the LC. As I previously mentioned, it just makes a quiet
ticking noise as if something is trying and failing to start. Ah well,
like the dead Sinclair Spectrum it will just have to be a "for show
only" exhibit in my personal museum until a replacement PSU comes my
way...

Thanks for the info.
