HP85: It works like a big computer, only it's yours

HP's 85, launched this year, was billed as a "scientific desktop" computer. It was built around the company's own proprietary CPU, running at a surprisingly-slow 0.625MHz. However, it apparently made up for it by having advanced software features aimed at scientific and technical users.

The machine actually came with a small built-in display, a thermal printer and some sort of magnetic tape storage. It was even supplied with a carrying case, which turned it into a "portable" computer - but only in the luggable sense of early portables, rather than being a laptop. 

It was apparently as easy to carry as your "attaché case", as long as that case was full of bricks at the time.
