Texas Instruments TI 99 / 4A (1981)

You are about to be introduced to the exciting new world of the personal computer. Until just a few years ago, the size, price, and complexity of computers put them beyond the reach of the individual purchaser. Today, Texas Instruments Personal Computers bring you remarkable computing power in affordable, compact units that can be easily set up in your home, office, or school.

Whether you have years of computer experience or have never worked with computers before, the innovative and flexible features of your computer offer you a wide variety of applications. Within minutes, you can begin using your computer to:

      • manage your personal resources
      • develop projects for home and business
      • bring new dimensions to education -- for you and your children
      • provide engaging new types of entertainment for the entire family
      • and much more.

POWERFUL TI BASIC

TI BASIC, a simple but very powerful computer language, is built right into your Texas Instruments Computer. With TI BASIC, you can develop and use your own computer programs for applications ranging from color graphics t statistical analysis and more. This language makes your TI computer a “true” computer -- not a video game or electronic toy.

CONVENIENT MODULE SYSTEM

The unique system of easy-to-use, snap-in Solid State Software Command Modules assures the continued versatility and usefulness of your computer. These rugged, all solid-state modules are completely preprogrammed for you. You just snap them in, and they “prompt” you through activities, applications, games, and entertainment. With a module plugged into the computer console, you can start using your computer immediately. You can choose from a wide selection of Command Module titles.

TAPE AND DISKETTE PROGRAMS

In addition to Command Modules, Texas Instruments offers a variety of convenient software on tape or diskette, ranging in complexity from simple games applications to high-level business and professional programs. Like Command Modules, these applications are ready for you to use, without any programming on your part. Programs on cassette tape require the Cassette Interface Cable to connect the computer and your cassette recorder, and diskette programs require the TI Disk Memory System.
