As far as I know the latest version of Interbase / Firebird that runs
on SCO is Interbase 5.x. I still use this version on the few SCO
systems that I still support. AFAIK it is no longer available.

I tried to compile an early version of Firebird for SCO but was
completely unsuccessful. I don't believe that the SCO specific code
exists anymore in the latest versions of Firebird.
