Short bit of history.

Swift was founded in the early 80's by a engineer, salesman extraordinaire, ex-Westinghouse/Millar engineer, by the name of Jean Pierre. The control that came out 1st was the Swift 5000. Available in either drive (GE300 or Generator) Configuration.

Dover and Otis put in several of these under a naming convention.

Otis = ModMaster
Dover = MicroModernizer 2 (MM2)

Both are identical to the Swift 5000 but with a name change.

Dover at the time was struggling to come up with a competitive Microprocessor based elevator. All they had to compete was the T2.

A deal was struck, allowing Dover to purchase copyright on all software, and hardware from Swift, and thus was born the T3, which for a few modifications is identical to the Swift 5000.

Dover which turned into Thyssen, still uses the same labeling convention for I/O's to this day on their elevators, and has purchased Swift outright for non-proprietary modernizations.

It Don't mean a thing if it aint got that swing.
