Robert,

Thanks for pointing this out. The link is for 1999.

Regarding WF1F/RITTY. 
 
The 1998 manual I have for WF1B (a DOS program) shows support for
RITTY as a DOS TSR.  Earlier manuals don't show it.  I recall trying
to get a sound card going in DOS.  It was a real bear-- at least for
the Soundblaster card I had.  TSR's were flaky too.

WF1B later became unusable as CPU speeds approached 1GHZ. It simply
quit.  Timing loop indicies became too large integers for their type
in the code.  Attempts to use "CPU slow down" programs to contiue to
use WF1B were not too successful.  The author had quit supporting WF1B
at that time.  The PASCAL source was available but nobody picked it up
to fix this.  RIP WF1B.

All this history sort of indicates the 1999 to be the start of useful
software/sound card RTTY for contesting or other use.
