Wordmark Systems is a small private company devoted to creating interesting
software and software like intellectual property (IP). Charles Marslett and his wife Cindy
established Wordmark Systems in 1982.
Since then Wordmark has implemented firmware and software for Atari and x86
computers.
Some of this software has become "abandonware" -- software no longer actively marketed --
and as the copyright owner, Wordmark, has made it available on this web site without any commitment
of support. We also have a few other links you might find useful.
Well, what is on this web site?
