A question for the Linux greybeards... I used ibcs2 extensively with 1.x and 2.{0,2,4} kernels in the '90s to run SCO Unix binaries. As far as I know, there never was official support for ibcs2 in 2.6-series kernels or later, so I might be stuck with 2.4.
So, which version is the latest ibcs2 for Linux? The latest version I could find is ibcs-2.1-981105.tar.gz on NTNU's tsx-11 mirror (https://ftp.nvg.ntnu.no/pub/mirrors/tsx-11.mit.edu/tsx-11/BETA/ibcs2/) - does anyone know a more recent one?
