Line 4: == Origin == BOS was one of four System/360 Operating System versions developed by the IBM General Products Division (GPD) in [[Endicott, New York]] to fill a gap at the low end of the System/360 line when it became apparent that OS/360 was not able to run on the smallest systems. [[IBM Basic Programming Support\|BPS (Basic Programming support)]] was designed to run on systems with a minimum of 8K8,192 bytes of memory and no disk. BOS was intended for disk systems with at least 8K8,192 bytes and one [[IBM 2311\|2311]] disk drive. [[DOS/360 and successors\|DOS and TOS]] were developed for systems with at least ~~16K~~16,384 bytes and either disks or tape drives. BOS was released in October 1965, nearly two years before OS/360,<ref>Pugh, Emerson, et al. "IBM's 360 and Early 370 Systems". MIT Press, 1991,p.331</ref> thus BOS was the only disk based operating system available at launch for a machine that was marketed as disk based.
