OS/2 users with version 2.11 or later of the OS have Indeo support
built in – which is what is needed to display these files. Check your
docs for the details.
If you need to unzip them, the most popular ZIP unarchiver is PKZIP,
found as PK204G.EXE in the "Compression/UU" library (#11) of our
Graphics Support Forum (GO GRAPHSUP). It will run in a DOS window on
your OS/2 session.
We also have a help file, authored by Bruce Herzog of our staff, which
can help you get it installed and running properly. GO GRFWELCOME and
check out the "Handling ZIP/ARC/UU" library (#16) for PK204G.TXT.
