Technical details

One of the oldest currently-maintained operating systems, MCP started life as a proprietary OS for Burroughs' large-scale systems. It was notable for its open source model, implementation of virtual memory and being written in high-level language in a time when most OSes were written in assembly language. Today MCP can be found running on Unisys mainframe systems.

Character details

MCP-tan is depicted as a tall, heavy-set woman, with a dark complexion, burgundy hair and orange-brown eyes. It's hard to say what her exact hairdo or style of dress is - unlike many vintage OS-tans, she is a very trend-conscious woman and tends to change her fashion often to keep up with the latest styles.

MCP-tan is known for her direct way of dealing with people and pragmatic personality; combined with her extreme self-reliance and hard-working work ethic, many people mistake her as introverted or uninterested in friendship. In reality she is a personable woman, but often gets too wrapped up in her professional life to have time for a social one. One of her closest friends is CANDE-kun, who works as her assistant.
