HAWG WILD Software, Box 7668, Little Rock, AR 72217, has a number of programs for the Timex/Sinclair computers of particular interest to hams.
One of these is a very nice code practice program written by KC9MR. This program comes in two versions on a high quality cassette. One version requires 16k of RAM while the other shortened version only requires 2K. Both versions appear on both sides of the tape and are accompanied by a short three page instruction leaflet.
The programs are very useful, flexible, and convenient to use. They could also be used to give the code test now that the volunteer examiner program is starting to take shape.
