Hp300

The HP300 "Amigo" is a computer produced by Hewlett Packard (HP) in the late 1970s based loosely on the stack-based HP3000. It was a commercial failure, massively so considering the huge engineering effort, but pioneered such ideas as multiple windows (on a character based screen), the idea of labels adjacent to vertically stacked user function keys, now used on ATMs and gas pumps. It also featured an 8" floppy disk, and a fixed 20M hard drive which was considered to be hard to back up. It featured screen editing for RPG.

The HP250, which was based on the desktop computers saw somewhat better success.
