MirageOS is a flash application designed for Texas Instruments' TI-83 Plus and TI-84 Plus series of graphing calculators. Although its name implies that it is an operating system, MirageOS actually works as a shell to manage and execute Z80 Assembly and TI-Basic programs in tandem with the default TI operating system. With the ability to run a variety of flash programs, MirageOS is one of the most advanced and user-friendly applications available for the TI-83 Plus and TI-84 Plus.
