Osborne 1 Portable Computer OCC1 – 1981 First-Ever Portable PC w/ Software, Docs
Step into the dawn of mobile computing with this Osborne 1 Model OCC1 — the world’s first commercially successful portable computer, released in April 1981. Created by tech pioneer Adam Osborne, this luggable system marked a turning point in computer history by putting a full office suite and operating system in a carry-on-sized case, at a game-changing sub-$2000 price point.
The Osborne 1 features a Zilog Z80 CPU, 64KB RAM, dual 5.25" floppy drives, a built-in 5" monochrome CRT display, and a detachable full-size keyboard. What truly set it apart: it shipped bundled with essential software like WordStar, SuperCalc, and MBASIC — an industry-first move that made it immediately productive out of the box.

- (2) Osborne software binders
- (2) Osborne 1 User’s Reference Guides
- (4) Additional manuals including MBASIC & dBase II Tutor
- (57) vintage floppy disks + (10) unopened Platinum Series floppies
