Man, that link's at least 4 years old ! I'm surprised any of those pages are still accessible. The author credits the 80scool list for helping him do the 350 install, so you'd be better off posting your query over there.
Christo, it wasn't so much the age of the page (only us old folks worry about memory!), as the accessibility that surprised me. The main geocities page was deleted, but I found this e-mail address (deleted - PM'ed to our French Connection) on a linked page.
