About This Manual
This manual shows you how to use your Tandy® 600. An overview of the
computer

The application chapters (2-6) each include atutorial for that application.
The samples in the tutorials are intended to familiarize you with the most
commonly-used features
ofthe programs.
Because of the complexity of the applications, the Telcom and Multiplan
tutorials are longer than the others. However, after going through the
tutorials for these 2applications, you should have athorough
