I'd bet it's 100% impossible to run 20 year old Sun software on anything.
The Sun 1 came out 19 years ago if memory serves me (1982). There isn't
much 20 year old Sun software, if any. :)

Sun's big trick is that a program that runs on any SPARC under a given
OS... runs on any SPARC. That wget binary you just built on an IPC will
run on E10k without modification assuming the E10k has an equal or later
OS. And I believe there's a fair bit of SunOS compatibility in the various
Solarises, although I don't know how far back it goes. I know I've run
SunOS 4.1.4 binaries on Solaris 2.5.1 without modification or

You might have a good chance of running ancient Sun software after a
recompile, assuming you had the libraries. But would you really want to?
