Well, compared to FreeBSD/NetBSD/OpenBSD, 4.1/4.2 are also the distant country cousins. The fact that 2BSD kept being supported long after even BSD4.4 was dead only makes it slightly more funny, if more anachronistic.

2.11BSD is close to dead now, though. I sent out a bunch of patches/fixes about half a year ago, but it was quite a long time before the previous patch set to that went out.
But we're at patch #448 or something like that, to 2.11BSD. A lot of 4.3 functionality was eventually backported to 2.11.

Hi all,

Can someone straighten me out on a few things.

1) Other than the tuhs/pups guys that seem to have archives of 2.11BSD,
is there a central place that manages source / build / patch trees ?
I've seen the "RetroBSD" guys running this on MIPS PIC32 stuff, but I
suspect from my readings thus far they don't much care about the 11
tree.

Eh. The obvious canonical source would be sms. Steve M. Schultz, who is the official maintainer. I don't remember where he keeps stuff, but that should be easy to locate.

Nobody cares about 2BSD except for the PDP-11 people, since 2BSD by now are rather distant in relation to all the "modern" BSD.

2) Was 2.11BSD ever ported to other platforms? Given the age/era, I'm
curious about 8088/8086/NECv20/80286 given the banked memory models used
and looking at the 8088/8086 XENIX disassembly.

Nope. That would not have been 2BSD then. And since the PDP-11 don't even have banked memory, it would probably cause some headaches to port 2BSD to something like 80286 or other similar machines.
To make it clear - the PDP-11 have a very normal MMU with pages.
