The Expensive Break Clock

One of our Tandy Model 100 computers had become relegated to controlling the buzzer for indicating shift changes, breaks and lunch. We used the signal for controlling the cassette interface to turn the buzzer on and off. A twenty line BASIC program was used to check the time against a schedule that was hard coded into the program.

Invariably for one reason or another this computer would forget the program. Either Bob or I would then run over and type the program in from memory, set the clock and get it running again. I cannot even count the number of times I did this while I worked there, but it was really no big deal because after a few times it only took a minute.

So here was have this computer which was originally purchased for more than $1000 and we were using it to blow a whistle 8 times a day. Nowaways this would be completely appropriate because you can buy a computer on a chip with all the power of the Model 100 for about $30.
