I’ve never worked with major enterprise or government systems where there’s aging mainframes — the type that get parodied for running COBOL. So, I’m completely ignorant, although fascinated. Are they power hogs? Are they wildly cheap to run? Are they even run as they were back in the day?
I used to operate an as400 mini frame from the 1980s and I want to say it it chugged close to a thousand Watts but I can’t tell you for certain, all I know is that when it was installed they put it on its own dedicated 15 amp line
