xmosaic 0.5–0.10 source code

Hello all,

I was wondering if anybody had the source code for NCSA xmosaic 0.5 (first
ever release) or any of the very early versions up to 0.10.  I can't find
it anywhere online and seems as though it's lost.  I've even tried
archive.org FTP backups of CERN and NCSA with no luck (seems they
self-deleted the early versions by the time the archives were taken).
Earliest xmosaic source I've found is 1.0.  Of course somebody has a copy
on some old HDD or archive.  I'm wondering if it would happen to be anyone
on this list?  Or if anyone has any leads?  Thanks.
