DOS-11, also known as BATCH-11 is an early and short-lived OS for the DEC PDP-11. It quickly lost support in favor of the user-friendlier RT-11.
DOS-11-tan has short light grey hair, pale green eyes, and round thick-rimmed glasses. She appears to be in her mid- or late teens, and is short for her apparent age. Unlike other DEC-tans, she has never been depicted wearing a military uniform, and instead wore pleated skirts with loafers, and a sweater-vest. She has some combat experience, as she taught her younger sisters sword-wielding, but it isn't specified if she ever fought in any campaigns in their faction's military. She frequently carried a knife with her.
Representing a difficult to use OS, DOS-11-tan had a temperamental and psychotic attitude, though she still cared for her family even if she often didn't show it.
Family and relationships
With the creation of a PDP-11-tan to be the mother of all the PDP-11 OSes, she was retconned to be the older sister to the other PDP-11 OSes. She was still their main caregiver; PDP-11-tan was too busy to look after her children, that she trusted DOS-11 to look after the others since she was the oldest. Unfortunately, DOS-11-tan was the least emotionally stable among them.
Background and history
DOS-11-tan was one of the oldest DEC members, and established the faction's tradition of sword-wielding. She taught RSTS and RSX the arts of sword-wielding, but wasn't so generous towards RT-11-tan, who she clashed with a lot. Her rivalry with one of her own daughters refers to DOS-11's abandonment by many users soon after the friendlier RT-11 in 1973, and could not stand for being upstaged. The rapid loss of support took its toll on her lifeforce, which she blamed RT-11-tan for, and ultimately passed away the next year.
