CTSS was a small, elegant timesharing system built for a modified IBM 7094 computer. It is considered one of the first timesharing systems. It was developed by MIT for use in the Computation Center.

While it had a short lifespan of only twelve years, CTSS proved to be prolific in its own right; it influenced most timesharing systems to come, most notably some IBM timesharing OSes, CP/CMS and Multics (the latter being considered a direct descendant). Multics was in fact built on CTSS machines, and was supported by CTSS until it was fully functional.

CTSS was open sourced in 2004; yet no emulators have been constructed to run it.

CTSS-tan is depicted as having wavy dark red hair, dark eyes, and glasses. She dressed in fashions that were inspired by Chinese designs, with a western twist. Her elegance of clothing is a reference to CTSS' relative simplicity when compared to its successors, especially Multics.

CTSS-tan's attitude was that of a kindly, caring woman, very mature and selfless. Confronted with her own eminent demise, she made it her life's work to care for the young Multics-tan when she couldn't care for herself; CTSS-tan also acted as her teacher, and the teacher of many young timesharing OS-tans of the day, like CP/CMS-tan, TSS/360-tan and ITS-tan. Through her slow deterioration she kept a serene, live-in-the-moment attitude; while CTSS-tan's life ended in 1973, her legacy lives on to this day and has no end in sight.
