Before there was HamTech or TheHammondForum there was ?MarkLongo's Hammond Mailing List. This Hammond Mailing List became known as The Hammond List (Hamtech) in April, 1997 when Mark Longo decided he could no longer spare the time required.

The Hammond Mailing List is (was) an informal internet mailing list for and by people interested in Hammond organs (old and new) and related issues. The purpose of the list is (was) to provide a forum for sharing general questions and answers, technical information, equipment reviews, etc., regarding the Hammond organ, it's clones, accessories, etc.

Archives of the old list can be found (courtesy of DonErickson) at:
