What is North Star Computers?
{{noref|date=March 2025}} '''North Star Computers''' was one of the earliest manufacturers of [[microcomputer]]s. Before they started making their first [[computer]], the ''North Star Horizon'', they made [[floppy disk]] drives for [[S-100 bus]] computers. They included a [[disk operating system]] called ''North Star DOS'' (or ''N*DOS''). The Horizon used the North Star disk controller and operating system. It was one of the first microcomputers that had [[multi-user]] features. Their second computer, called the ''North Star Advantage'', ran [[CP/M]], and had the keyboard and monitor built-in. The graphics were very powerful for their time. When the [[IBM PC]] came out, North Star made an [[MS-DOS]] compatible processor card that could be added to the ''Advantage''. Their third computer, the ''North Star Dimension'', was multi-user like the ''Horizon'', but [[MS-DOS]] based. Because their products in the early [[1980s]] were only [[MS-DOS]] compatible, not fully [[PC compatible]], they never sold very many, and the company went out of business.
