1. Create a better UNIX than UNIX. UNIX microcomputer market forms as a side-effect due to marketing.
2. Move UNIX features into CP/M in MS-DOS.
3. Clone OpenVMS architecture with enhancements and emulators for older OS's.
4. Develop on OS/2 for better reliability, pace, and inspiration. I'm sure OS/2 stuff ended up in NT past the emulator. I'd be interested in a link that went into that in detail.
5. Run mail and gateways on Xenix as UNIX was great at that sort of thing.
6. Run whole business on a single AS/400 that just gets shit done mainframe-style.
7. Replace all of the above with one product that has key attributes of all of them in usable package on cheaper hardware.
They don't look as dumb now as I thought when I was younger comparing MS-DOS to BSD's or Linux. ;)
re Linux
The author asserts multiple times that Linux comes from Xenix somehow but didn't seem to prove it. Says the architecture, standard, and microcomputer UNIX was first done by Xenix. Then Linux did one. Past that, nothing. Is there some resource with specific evidence that Linus got Linux design aspects from Xenix as opposed to another UNIX? And my original sources said he started with Minix changing stuff in his design that didn't suit his hardware or needs. So that needs to be factored in.
