I got that one thanks Jeremy from an archive of the old Yahoo group (The Electric Handbag).
Unfortunately, as you say, once you zoom in it goes to
and turns in to a blurred mess.
I also got a pdf (3 separate pages) which you can zoom in quite way and it stays mostly legible, but there are some spots where it is very indistinct, like where things on page folds tend to lose clarity.
I did try to join The Electric Handbag in it's new home on Groups IO but it looks like it has fallen by the wayside unfortunately as I didn't get any response to the request.
