UltOS is a work-in-progress graphical operating system for the Commodore compatible Ultimate 64 and UII+ cartridges developed by Gideon Zweijtzer, intended to take advantage of the machines native feature set.
It will currently run on a standard C64 with 17xx REU and 1351 mouse.
To compile the source:
Requires latest version of 64TASS. On a Windows machine, just run the build.bat script. Ill work on a make file for other operating systems soon.
The current d64 image is in the target directory.
