SF Net

SF NET Coffee House Network was an electronic bulletin board system created by Wayne Gregori in San Francisco, California in July 1991.

[6] The coffee shop terminals were the culmination of a series of clever solutions to the problems of long-term remote placement in areas marked by low supervision and a young crowd.

According to the then-popular Boardwatch magazine, the inexpensive, hence replaceable PC XT sat inside a locked plywood cabinet with vandalism-resistant Zolatone[7] paint and "keyboard condoms," or spill-resistant rubber coverings.

Wayne Gregori engaged David Lahti as a friend and fellow visionary to help develop and operator of a popular San Francisco BBS, to develop and maintain the code base for the cafe table's communications software named, TableTalk, the BBS code base was maintained by Gregori.

Lahti and Gregori developed and introduced a handshake between the coffee shop terminals and the BBS to distinguish them from other callers, ensuring paying customers could continue to use dedicated lines.
