Now it can be told.

These pictures were taken in the computer room of a hospital where I used to work. There was some very, very old computer machinery still in use, including a Data General mainframe that utilized a reel-to-reel tape drive.

The most striking sight in the computer room was the presence of 40 interconnected 12-volt car batteries that made up the battery backup system. Here’s a closer look.

Who even uses car batteries as a means of battery backup anymore? It’s been 3 years since I lost my job at this hospital and can only wonder how much things have changed since. Surely they’ve scrapped the Data General mainframe by now, but I don’t know about the car batteries.
