Tried Alan's Restore516 after placing it on the hard-drive (root
directory). Screen message indicated a successful restore and told me to
re-boot which I did. I now have a screenful of vertical black, purple, red
and green bands with a broad black horizontal band across the top and the
bottom of the screen, both approximately one sixth of the screen height.
When I try re-booting I get as far as the "clunk" (which I think I
remember as being the floppy drive) after about 2 seconds but no beep.
There is a screen message saying "signal frequency is out of range. H:
41.7KHz V: 79.4KHz. Please change signal timing."
