OS8
From OS-Tan Collections Wiki
Mac OS 8 is a character occasionally seen at Futaba Channel. She is known as OS8-tan, whose hat's colors are based on the rainbow Apple logo of the classic Macintosh. She is rarely seen, and pictures of her are only available at an old archive specializing in the Mac OS girls. It can be found at http://evo7gt-a.hp.infoseek.co.jp/osmac/.
