During the early 80's, before the IBM compatible PC and Apple Ii, there were two companies that made 'luggable' computers
The Osborne 1 resembled nothing more than an hard-sided suitcase. It weighed 23.5 pounds and came with a built-in keyboard (that also functioned as the unit's fold-down lid) and tiny 5-inch monochrome CRT monitor that displayed 52 characters by 24 lines.
Kaypro's first market-ready computer, in 1982, was called the Kaypro II. (The Kaypro 1 never made it to market.) Like the Osborne 1, it was a "portable (in name only) that ran CP/M on a 2.5 MHz Z80 CPU, with 64 Kb of RAM. It featured a fold-down keyboard and built-in monochrome CRT display, and weighed 29 pounds
The Kaypro II upped the ante, however, with a larger 9-inch screen with 80 column display. In addition, it included single-sided/double-density 5 1/4-inch disk drives
