Re: Back in the 1990's...
A friend worked at home with the PC next to an open window overlooking a dusty country road. She also had two large dogs who moulted their long coats for the summer. She was also a chain smoker.
Needless to say doing an upgrade on her PC was definitely unhealthy. Communication could be difficult too. The open window caught the full impact of international flights with their undercarriage down as they approached the runaway about 1 mile distant.
She also had the novel problem of burning out modems. In the end a spark arrester solved that problem - presumably lightning induced.
