I think I see the problem
Years ago I worked for a company supplying industrial process control equipment. It was all run by DEC PDP computers (I said it was years ago) which were floor-standing, cupboard-sized minicomputers.

One day we got a call from a customer who couldn't get their system started. After running through all our checks, it seemed that it must be a hardware problem so we contacted DEC to get one of their engineers to go and have a look.

A couple of hours later we got a call from the DEC engineer. In the original phone call, which lasted over an hour, at no point did the customer think it was necessary to mention that the computer room was currently six inches deep in water, due to a burst pipe...

Ahh, the Burroughs equivalent.
32 serial terminals hung off the back. Four power supplies requiring four power leads, not a cascade of power splitters.
No bloody wonder it kept blowing the fuse. It's startup current was close to 20amps.
'We needed the plug sockets' was the feeble response.
Two days later and I'm back on site removing the four way extension lead and replugging it into four separate sockets.
Six months later, it got replaced by a new fangled Pentium machine and a new serial multiplexer. To the Burroughs credit, it did run faultlessly for 20 years.
