Can Ubuntu Linux run SCO UNIX OpenServer 5.0.7 applications like filePro? Can I use CTAR to copy application directories from a CTAR backup tape to Linux Ubuntu?

Supposedly there is a binary emulation support that is available to the Linux kernel though it needs to be compiled in. I've always found though that it is better to port the application or run a native alternative then try running through an emulator.

This binary emulation was dropped a while ago, before Ubuntu even existed. This has been discussed here. – Gilles Sep 17 '12 at 22:45

I never tried it, but you might have more luck with NetBSD, which has more powerful binary emulation features. It claims to support SCO UNIX binaries; you might need to supply your own libraries.
