Here at work we still have some binaries from HP-UX 6 that run on HP-UX 11. Now thats amazing.

Cool. VMS and VM/MVS/TSO/<insert magic IBM acronym> are similar.

Now *those* are goals worth emulating.

Heck, they probably aren't even that hard anymore. Using something like bochs you could probably kick off a captive instance of Linux/FreeBSD/etc to actually execute using a model of really old hardware.

Now, *that* would be backward compatibility. Install a new FreeBSD 5 box. Take a memory image of the old machine; transfer memory image to captive emulator on new machine; press continue.

Hmmmm. The only problem with that is the lack of open documentation about the hardware. Interesting, I wonder when that is going to hit critical mass.
