iBCS64 is no longer maintained.
It has been replaced by the
ibcs-us,
a user-space implementation of the same thing.
iBCS (Intel Binary Compatibility System) allows an Linux x86/AMD64 kernel to emulate at the following Unix systems at the system call level: xenix, ibcs, isc, sco, solaris, svr4, util, uw7 and wyse.
This is a fork of the sourceforge Linux-ABI, whose committers have gone awol. It adds debian packaging, and improved documentation. If you have added to the patch collection of Linux-ABI you welcome to commit rights here - just ask.
There is a change log and a README.
