Heavy...
One of my early jobs was on a helpdesk and the client decided to throw out all of its old kit. It was to be collected in a spare office space at the end of one wing. I spent ages carrying old desktops and towers around the building to the space. Then I got onto the printers, a couple of old BJs and an IBM ProPrinter, no big deal...
Then I found an ancient HP LaserJet. No, I didn't forget the model number, an original LaserJet - the same chasis as the original Canon laser printer and Apple LaserWriter, but without the PostScript module.
It was all the way over the other side of the building, down the other wing. 100M along the wing, 200M across the building and 100M down the other wing to the open space, through 4 security doors with PIN entry pads. And no wagon to transport it with. I had to carry the damned thing the whole way! All ~50-60Kg of it! Its successor, the LaserJet II was about half as heavy (~35KG, ISTR) and the manual said it was to only be transported by 2 people.
