The article mentions that it was the first computer to use printed circuit boards. I have the October 1953 IRE (now IEEE) Proceedings at home, which describes the SEAC from where this computer design was derived. I can look it up in a couple days.

Yep. It was a 12-ton portable computer accompanied by an 8-ton power brick.

11 tons for the computer, 1 ton for the Solari style display:
