OS/architecture help needed

[a1s2d3f4g5]

Can anyone help me figure out what OS/Achitecture the files in blast2.spp.tar.Z in this folder: http://www.advbiocomp.com/blast/obsolete/even-more-obsolete/ have been compiled for?

Many thanks.

The software was written to work with any POSIX compliant UNIX client, including Linux on a modern X86 chip.

There were special versions for IRIX and DCE Linux due to some threading weirdness, I think.

But as far as this specific compiled version, I don't know for sure.
