Litespeed catalog location(s) are mostly obsolete too.
MOMBAT and TiRides were the sources, and MOMBAT sourced theirs from TiRides if I recall correctly.
Really liked both sites when they were active. Learned a lot.
Tried to upload a few Litespeed catalogs the TiRides site didn't have, but the site owner/creator never responded to my site messages.
Bummer.
