Since many teachers have had little or no exposure to computers in general and to the TRS80 in particular, this section is designed to help you understand the system. The Radio Shack TRS80 is a compact system, made up of four components.
A keyboard unit, which looks like a typewriter, contains the actual computing circuiting, called the “central processing unit”.
A video monitor, which looks like a television screen, is specifically designed for use with the TRS 80. It differs from a standard television in two respects: It has a broader bandwidth than most “home TV’s”, a characteristic which produces sharper screen images for greater legibility of the display, and does not contain a tuner.
A cassette recorder which looks like and is a tape recorder. The recorder is a standard audio recorder which was chosen for its compatibility with the TRS80 and has been modified somewhat for this use.
The power supply powers the keyboard unit. Using a separate power supply eliminates bulk, size, and heat in the keyboard design,
What follows are computer programs that look into the Connecticut Daily Numbers.
Appendix I has a complete printout of the data deck used with all the programs in this unit.
