It's interesting that the first modernization ideas for the OS/kernel date back to 1994, just right after the official release of the first Power Macs (6100, 7100 and 8100). Another interesting point is that NuKernel working group doesn't include Gary Davidian that wrote the NK v1.</div><div><br></div><div>What is this "alternate" Virtual Memory API?

The entire External Reference Specification for NuKernel (c 1993) is<br>
included as an appendix. It seems that the later additions to the<br>
kernel, which were under-utilised by Mac OS 9, were an increasingly<br>
faithful replication of NuKernel mechanisms.<br>
