      4  * This is a *real* hack to dump the topaz80 kernel font. This one is
      5  * ways nicer than the ugly Mach font, but we'll have to dump it from a
      6  * running system to not run against Commodore copyrights. *NEVER* distribute
      7  * the generated font with BSD, always regenerate!
