Huh. Didn’t know that about OS/2’s popularity among sysops. One of Temple’s BBSes (Waverley Park) presented what I now think was a Unix shell, or at least supposed to look like one, but I can’t imagine they were actually running Linux (ca. 1993)
TENet was the beginning of the end of my BBS days, with its real email and fancy WWW browser - lynx.
Full circle: being the old lady on the team talking about the digital American wild west of the 90s with BBSes (the saloons) and town ISPs (the general stores) to young German colleagues who have known nothing other than gradually increasing Telekom DSL speeds. (Texpats in Germany, represent!)
