Last week we saw the official release of the C64 OS v1.0. What is C64 OS you say? C64 OS is the brainchild of Gregory Nacu and he’s been working on the project for the last five years. In a nutshell, C64 OS is a modern operating system add-on designed to balance power and add the modern ease of use we have on PCs to the C64. This sounds similar to the first couple of versions of Windows which were overlayed on top of MS-DOS.

A licensed copy of C64 OS v1.0 includes:
