HP 300
The HP 300 "Amigo" was a computer produced by Hewlett Packard (HP) in the late 1970s based loosely on the stack-based HP 3000, but with virtual memory for both code and data. The HP300 was cut-short from being a commercial success despite the huge engineering effort, which included HP-developed and -manufactured silicon on sapphire (SOS) processor and I/O chips.
The HP300 was initially designed as a single-user workstation by a totally separate program within the General Systems Division (GSD), the Cupertino, CA home of the HP 3000 business computers (the division was later renamed Computer Systems Division CSY). Later, the HP300 design team developed multi-user abilities, and an ahead of its time inter-unit processor interconnect that let one HP300 change registers in other inter-connected HP300's system.

The circuit boards were in a floor pedestal box, with CRT on top with built-in soft keys, and fixed keyboard protruding in front. It pioneered such ideas as built-in networking, automatic spelling correction, multiple windows (on a character based screen), and labels adjacent to vertically stacked user function keys, now used on ATMs and gas pumps.
The HP300 featured HP-IB (later IEEE-488) interface (IF) as the I/O bus, an 8" floppy disk, and a built-in fixed 12M hard drive. Later drivers for HP7970E tape drive allowed for easier HP300 system back ups. It also had a native system programming language, a database, BASIC, and featured screen editing for RPG.
