This odd little Windows program allows you to translate text on the Clipboard into a textual representation of Morse code (dots and dashes), or vice versa. Stranger still, it even lets you play back this Morse code over your computer speakers, if you have a sound card. Requires Windows 3.1 or later, Windows 95, or Windows NT, and appropriate sound equipment (a sound card—I tested it with a Sound Blaster™—and speakers or headphones or something).

This program lets you play the “Knight’s tour.” The Knight’s tour is a game in which you attempt to move a chess knight around a chessboard so that it covers each square once and only once. It sounds easy, but if you’ve never tried it before, you’ll probably find it harder than you expected. This program lets you take back your moves, so you can cheat if you become frustrated. This program requires Windows 3.1 or later, Windows 95, or Windows NT.

This very simple program, which you must execute inside a DOS command window, simply prints the date and time once each second, and produces a series of variable beeps inspired by the audio time signals broadcast by the NIST in the United States from radio station WWV in Fort Collins, Colorado. Press CTRL/C to stop it. I use the program to check time sychronization on multiple Windows machines by ear. You must be running a 32-bit version of Windows (not an old Windows 3.1 or anything like that), and if you are running Windows 9x or Windows ME, all the beeps will be the same (which doesn't sound very interesting). Functionally this program is identical to the UNIX version, below.

Press CTRL/C to stop it. I use the program to check time sychronization on multiple UNIX machines by ear. I tested it on FreeBSD, but it should work on lots of UNIX systems. gcc can be used to compile it (be sure to use the -lm option). You need to have /dev/speaker configured and writable from the account running the program. Functionally it is identical to the Windows version, above.
