>Another fun alt-history branch is the one Sun manages to sell thousands of Amigas as low-end Unix workstations, moving Unix down into the personal computer space, and saving Commodore.

This never would have happened with the 3000UX, and various websites are guilty of passing on nonsense (like Sun actually having designed the darn thing). Amiga by this time had already fallen behind Apple's 68K offerings. There is no time in history when the 3000UX was competitive with Sun's own products. By this time Sun had three separate offerings (SunOS on SPARC, SunOS on 80386, and PC/IX on 80386) and would not have added another which, again, was technologically behind and incompatible with Sun's own products.

Maybe. Sun could have acquired Commodore in 1984 or 1985 and Dave Miner and the blitter/copper, and gone a bit more the SGI route.

Also, Commodore did the first SVR4 port outside the Labs, and Sun ended up doing the first commercially successful port of SVR4 (Solaris). So it's not that crazy.

(I think the SVR4 porting was probably a mistake. At Sun we had a pejorative for a lot of the garbage in SVR4: "it came from New Jersey".)

You mean acquire Amiga. Commodore in 1984 was far larger than the brand new Sun. But yes, that is a very intriguing path not taken.

You obviously are on the West Coast side of the Berkeley/Bell Labs divide. Was there a lot of internal discussion/dissension before/during the SunOS/Solaris transition?

No, I joined Sun long after the SunOS 4 -> Solaris 2 transition. The "it came from New Jersey" thing was just a pejorative phrase we used for ugly code with ugly code smells that came from SVR4. It was certainly not my coinage, but rather something Sun's greybeards would say. I had occasion to say it myself.

Basically STREAMS and XTI were disasters that took two decades to eradicate. But there was plenty of stuff in userland that wasn't great either. I recall a bug in eqn once that elicited that comment from someone.

> Was there a lot of internal discussion/dissension before/during the SunOS/Solaris transition?

There was plenty of evidence of internal dissent still a decade after the transition. SVR4 just wasn't all that great. And really, Solaris did not resemble SVR4 that much anymore 20 years after the transition. However, Sun was able to make Solaris quite good in spite of SVR4.

Ultimately I think the transition was good for Sun though. More than anything the user-land of SVR4 was fundamentally different from that of BSD primarily because of ELF, and I think ELF was a fantastic improvement over static linking (at the time, and even now because the linkers haven't adopted any of ELF's semantics wins for static linking, though they could).

Another path not taken is the Commodore 900 <https://en.wikipedia.org/wiki/Commodore_900> running Coherent. If Sun buys Amiga, perhaps Commodore goes ahead with it and eventually dominates the world via Unix(like)!
