Part 4 appeared in issue 141. There were 8 parts in all. I don't know why only 1,2,3 and 5 were put up on the site, as this ahppened about five years ago.
Part 6 was in issue 146 and part 7 was in issue 147. Part 8 was in issue 158 (there was a big gap when David took over as editor of ME).
I'm afraid I don't have the original copy it isn't going to be practical to put them all up as articles, due to the time required to extract the text and pictures. They can all be found in the archives.
