I know at least two people who were interested in checking out the latest ndk sources, and so I've decided to clean them up a little, and put them on my web site.

Major changes to v0.05:
run-time linking of rdoff2 objects into kernel
page-based memory management (using stacks)
text-mode "faux-graphics" plasma boot-up screen
start of vm86 code (needs a lot more work)
bugfixes
Check out the /src/oneSemiColon file for a laugh. All those errors were caused by (wait for it!) ONE missing semi-colon. After removing it, you can see it compiled perfectly fine.
