DOS/360 - now called VSE - originated as a humble disk-based single-tasking operating system on the IBM System/360 mainframe. It had a small memory-footprint, allowing it to run on lower-end System/360 models incapable of handling OS/360. Later versions of DOS/360 incorporated multitasking and other advanced features, and its modern day incarnation - z/VSE - is still used and developed today.
At one point, DOS/360 was the most common OS in use.
DOS/360-tan is depicted as a somewhat tall, lightly-built woman with long light grey hair. The most mature-looking member of the /360-tan family, she dresses professionally, preferring women's business-suits to the elaborate dresses her sister OS/360-tan favors. She is physically fast and strong, although she needs glasses and is somewhat hearing-impaired.
DOS/360-tan is generally easy-going, loyal and trustworthy, traits that have gained her a devoted following of users, terminals and a place as OS/360-tan's right-hand woman; indeed, she is one of the few people OS/360-tan thinks highly of and considers an equal. Due to her role in IBM intelligence (and work as a scout) she is quite apt at manipulation and subterfuge, talents assisted by her excellent speaking skills. Despite her verbal fluency, she has near-indecipherable handwriting.
