Z3 – The Zork CPU
Is there an overview of the <i>evolution</i> of the Z-Machine through the years—what features were added and how the architecture changed in each version, and what these changes allowed that was previously difficult?<p>It'd also be interesting to see similar "release notes" for proprietary game VMs, like the runtimes of Game Maker Studio or RPG Maker—though these would probably have to be the result of reverse-engineering + wild-ass guessing.
