>>.  Back in the 1980's, an obscure product called Model 204 used to sponsor big conventions in pleasant places and hire totally non-IT people to speak at the lunches. You might have enjoyed the famous New Orleans Chef named Justin-something-or-other talk about his old ModelT. <<

Justin Wilson, the Cookin' Cajun! Had a great PBS show at the time. Model 204 was an inverted file system database. They never got commercial success even with a really great product because their biggest customers were CIA and NSA.

In the Cold War days, those guys did not want a lot of people knowing what they used, how big the DBs were or anything else. One of the "urban myth" stories about 204 was that a salesman approached the Russians about buying the software. The next week, he was drafted and sent to the DEW line.
