			The Furguson Big Board (FBB) was a computer board designed for hobbyists. The FBB was a direct progenitor of the Kaypro II mainboard. Kaypro did not license this design but based on the schematics and layout of both boards it is clear. [https://retrocmp.de/kaypro/kay-p2%20hrdw.htm See RetroCMP for further details]

			The Osborne 1 shipped in July 1981. It appears that Non-Linear Systems was already developing the Kaypro II by this point but it is certain that the Osborne 1 influenced the final version version of NLS's machine.<br>The weaknesses of the Osbourne 1 was it's 5 inch screen and single density floppy drives.

			The Executive was a upgraded Osbourne 1 that improved the Osbourne line to be more competitive with the Kaypro by increasing the screen from 5 to 7 inches (the Kaypro was a 9 inch screen) and double density floppy drives. It was introduced in April of 1983.<br>
			Osbourne filed for bankruptcy in September of 1983.
