Mac SE screen - test-drb@ccmp.vtda.org

Ta for that, but I've already got a v.clean classic and the SE will buff up
quite nicely when I get the time!

 Adrian,

    Too bad you're in the UK. I have a nice Classic and a nice 
 SE that are
 looking for homes.

 Well, not only was the screen dead but the

 for the screens in the Plus, SE and Classic were
the same, except the
classic was a slightly different sub-variant (E instead of   D). I installed
 the Classic CRT and got nothing, nix, nada, so I
figured if   the Classic was
 mostly dead it was OK to assume the screen was
too. I only   thought about the
 analogue board when I'd installed the Plus
screen, so I   swapped that too and
 hey presto - working SE. I then put the Classic
screen in   the Plus and that
 works too, so there's now a completely dead
Classic   available (well, the
 mobo might be OK) as well as the bones of an SE!
There's no   point in keeping
 the bust CRTs since they're beyond repair.

 The resolution shouldn't matter for a monochrome CRT (there are no 
 phosphor dots/stripes on such a screen). The resolution is really 
 determined by the driver electronics, although the yoke is 
 likely to be 
 different as well (different scan rates -> different yoke 
 inducatance, etc)

  The good old british postal service
'happened' to the other   CRT. They

 Ah... That explains it :-(
