SCO OPENSERVER

[American Eye Center]

I just had a really quick question, the company I work for uses a 
software that runs on SCO Openserver 5, or later, I have read that 
Freebsd is compatible with software written for SCO OpenServer, I just 
wanted some specs as to how compatible you are, the software vendor is 
being shitty and won't say if there software will run on freebsd, they 
want us to get sco openserver(i wonder why), freebsd is far superior, 
and not to mention CHEAPER.  Thanks
