@denix @sjvn I’ve been “online” since using a DEC PDP-1103 using a hardwired physical dialup beginning in late 1979 via a GTE Sylvania “intranet”. We were all connected to transfer our lab results from remote locations back to the home base in Towanda NY. Baud rate was really really really low.
I remember using DOS, later Spry Mosaic w Windows and connecting to NASA using a fast 1200 baud modem in 1990 - 1992 or so. Fun times.
