OOOOOOOPs there seems to have been a slight glitch, sorry about the
empty posting earlier! :-)

I did want to warn people of the dangers of a DIY upgrade (520 -->
1040). I did this very thing. The kit I bought was described in the
mag as an easy project that anyone (with a little experience) could
do. When the kit arrived it looked fine. In fact the fitting process
seemed quite simple, if a little labourious. The problems came when I
turned the machine on after re-assembling it. All I got was a blank
black screen! After much probing I could not find anything wrong with
it so off to the repairers it went. Eventually I got it back working
with a full meg, phewww.

The main problem with the kit was that you had to solder sockets onto
the board. These sat so closely together that it was nigh on
impossible to see if two pins had been soldered together (I suspect
that this was the problem with mine).

So, my advice to anyone trying to upgrade is, unless you *really* know
what you are doing when you pick up a soldering iron, get it done by
the dealer/upgrade supplier even if it costs 10-15 pounds more. It
would have saved me ~40 pounds!

Frank.
