The Univac office was at a major intersection with a storefront on two sides. The Univac II was their latest and greatest, so it occupied the store front with big grey boxes. The console was the size of a two pedestal desk with lots of flashing lights and an electric typewriter of that era.
The processor was a huge box about six feet high with triple redundant chassis containing vacuum tubes in balanced stages. Needless to say, it was cooled by fans blowing over a large coil of pipes containing chilled water. The line printer was another large box full of tubes and hammer modules with a drum containing only upper case letters. Data in those days was 6-bit. I don't know how this printer's buffer worked, but one printer of that era had a mercury delay line for the buffer memory. This is a pipe filled with liquid mercury and they created standing waves in it for the data.
The magnetic tape drives were about six feet tall and three feet wide and they had six of them. Magnetic tape in those days was made of steel foil. If there was a permanent error on the tape, the drive punched a hole in the tape, spaced a few inches and punched another one. These were sensed by air flow, and skipped when the tape was being processed. It took two men and a boy to change these tapes, which was hardly ever. There were no disks, but there was drum storage that had about 17 million six-bit characters each, one head per track.
A funny thing about this machine was if there was a power failure. The cooling coil would sweat and drip onto the floor of the system enclosure. Before power could be applied again, the operator had to take a bucket and mop out the enclosure to prevent short circuits in the condensation water.
The main memory was another large box full of large core memory. I think it has something like 128K 6-bit positions.
This system was less powerful than the cheapest smart phone of today, but it cost millions of dollars.
When I was working for another company we had two of this "big" fastrand drums that were supposed to be the residency for the operating system, but when we powered them up for the first time the heads fell on the surface and scored it all around (both drums). Needless to say they were just lumps of iron after that.
