This has certainly been my experience as well with mature, for the era, BSD
ports.  Most of the problems I have encountered have been with TCP/IP
issues in 2.11BSD and Ultrix 3.1 related to traffic they were never

I think our expectations of a 16 bit Unix are going to be well out of
proportion now.  When 16 and 32 bit Unix systems existed side by side it
was easy to consider the resource limitations of both when programming.
Now that 16 bit systems have moved completely out of general end user space
we only consider the constraints of the 32 and 64 bit systems that exist
side by side.

Some of my interests lie in preserving early '90s hardware with original
operating systems, and working within their constraints.  Porting modern
tools to SunOS 4 or Ultrix 4 or IRIX 4 (huh, everyone really was stuck on
the same version) is a challenge but it can be done, as long as those tools
do not necessarily rely on shared libraries.  Backporting C99 to C89 is
often not as difficult as it would seem, though it can sometimes be
laborious.  On the other hand, porting modern tools to my PDP 11/23 running
2.9BSD is a total non-starter for reasons that I am sure I do not have to
elaborate upon here.
