VERY first one, I believe, (Ragge?) for NetBSD/vax.
True. I had two of them, one running 4.3 Reno and compiling the system and the other for test booting, using a dual-ported RP06 :-)
   Let us not be too quick to de-support for the sake of de-supporting.
The maintenance and testing overhead is minimal.  The latter can be ZERO
if we put it on the users of, say, VAX-11/750s, to do the testing on
those machines and report bugs, preferably with patches. (I will, once I
get my 11/750 reassembled)
There are a bunch of things that causes bloat but lacking them makes systems almost unusable. Compiling things on 4.3BSD systems is really a pain since most SW today expect things like language support, threads, tons of new libc routines etc.

There are also the fact that people writing modern SW often do not care about execution speed, since it anyway is fast enough on modern hardware.
