DigitaOS

DigitaOS was a short lived digital camera operating system created by Flashpoint Technology and used on various Kodak, Pentax, and HP cameras in the late 1990s. DigitaOS debuted with the Kodak DC220 on , and was released on a total of 11 camera models before it was abandoned in 2001. DigitaOS was notable for its ability to run third party software, a concept that was not again realized until the release of various Android based digital cameras in the early 2010s.
DigitaOS applications were programmed either as JIT compiled scripts using "Digita Script", or AOT compiled programs written in C using an official SDK. The operating system abstracted away most camera functionality and hardware platform differences, allowing software to be compatible with most DigitaOS cameras. Additionally, DigitaOS handled the GUI presented to the user and basic camera functionality.
Because of its ability to run third party software, several games were ported to it. The most notable of these being DOOM and MAME.
