rpix86 is a DOS emulator for the Raspberry Pi created by Patrick Aalto. rpix86 emulates an Intel 80486 x86 CPU running at 20MHz with 640kB of memory, 256-color Super VGA graphics at 640x480, and a Sound Blaster 2.0 sound card.[1] [2] The latest version is 0.19, which was released in June 2015.[3]
rpix86 does not have an inbuilt command-line interpreter. The user needs to have a DOS program that provides the command shell features. Currently the only supported shell is 4DOS version 7.50.
