There’s a legend about a company accidentally walling-off a VAX server, and it continued to hum along.
It’s no longer a legend — I have found an eyewitness!
Keating Floyd (Keating_floyd-at-onebox-dot-com) is a consultant. He was visiting B&W Tobacco in Macon, Georgia in 1998 or so. The client was ripping out drywall, and discovered a VAX that no one knew about. It was still running and serving clients.
Sorry — no pictures available. And he didn’t know what application was running. But, hey, it was running VMS, for sure!
