In the late 1970s, we used dial up modems (the kind with the klunky acoustic coupler) to dial into Honeywell's response center to close out repair calls. I also discovered they had games on the response center computer and was able to entertain myself on quiet night shifts by playing Adventure and Star Trek on a TI Silent 700 terminal.

Some of the mainframes we servicced were also connected to ARPANET which provided networked access to university and various government agencies. I know there was an ARPANET worm around 1980. Not sure if there was hacking prior to that.
