Public Domain Software Info Wanted

[Pat M. Iurilli]

Does anyone have any information on any public domain software available
for both the IBM PC and for UNIX?  I'm interested in things like
spreadsheets, DBMS, compilers, logo, commands, games, etc.  Please respond by
electronic mail and I'll summarize on the net, unless expressly askes not to.
