Reminds me.. Worked for a computer service company, early 90s, it was mostly RS232 serial terminals, with a bit of ARCNET between the servers. So much ended up connected by flat ribbon cable placed under the carpet tiles! This was a new build, designed by the company owner, and he didn't include any provision for computer cabling! Phones, yes, but no data. We were pinning trunking to the walls within the first week of moving in..
