Anyway, I went though everything and made sure that all the pages are now accessible... I think.
Now, all of the information on this site has either been extracted from the scraps of documentation that I've got, from my failing memory or from information that readers have supplied. If you spot anything that isn't clear or just plain wrong, PLEASE let me know so I can correct it. None of us are getting any younger and if this information isn't recorded soon it may be lost forever.
Likewise, if you've been squirreling documentation under your bed please let me know. I'll happily take it off your hands and give it a good home, or scan it and return it to you if that's your wish. Whatever I get hold of will end up on this site... eventually.
