Everhart) writes about generating musical tones using hardware not really I recall a program for the TRS-80 Model I that performed a nice trick. Unlike the VIC's and C-64's, the TRS-80's would use a regular casette tape player for storing programs. The speaker and microphone in your tape player were, of course, extraneous. This program, however, would "click" the speaker and listen for "clicks" on the microphone --- sonar! You could hold your tape player near a wall, and see a bar graph on the computer screen showing how far away from the wall your tape player was! As I recall, it worked well for distances up to about four inches. -- Jim Northrup nort...@wpi.wpi.edu Assistant Professor, Department of Mathematical Sciences Worcester Polytechnic Institute, Worcester MA 01609 I wish I could hear the soundtrack to my life. Then I would know when to duck.
