You can find mentionings of 32-bit capable S1 in trade publications (Computerworld, Datamation, etc.) in the mid-80s timeframe, and there is an S1 button on eBay right now with the words "multi user, multi nodal, multi tasking, multi processing". In a quick scan, I saw announcements of some S1 OEM agreements, including Phillips Medical. It was a product of Multi Solutions, a startup out of Lawrenceville, NJ, so you'd sort of assume that some Bell Labs talent was on staff. S1 was trademarked in 1986, it expired in 1993.
