Also, the phone company can make changes to its lines, equipment, operations, or procedures that could affect the op- eration of this system. The telephone company notifies you of these changes in advance, so you can take the necessary steps to prevent interruption of your telephone service.

This equipment complies with the limits for a Class B digital de- vice as specified in Part 15 of FCC Rules. These limits provide reasonable protection against radio and TV interference in a residential area. However, your equipment might cause TV or radio interference even when it is operating properly. To elimi- nate interference, you can try one or more of the following cor- rective measures:

•Reorient or relocate the TV or radio’s receiving antenna.

•Increase the distance between the equipment and the radio or TV.

•Use outlets on different electrical circuits for the equip- ment and the radio or TV.

Consult your local RadioShack store if the problem continues.

System 350 specifications

The Radio Shack System 350, introduced in the mid-1980s, represents a significant milestone in personal computing, combining a blend of innovative features, robust technology, and user-friendly characteristics. Designed primarily for educational and business applications, the System 350 marked a notable entry point for many users into the world of computing.

One of the standout features of the System 350 was its use of MS-DOS, an operating system that provided a familiar interface for a multitude of software applications. This characteristic allowed it to run a wide range of productivity tools, from word processors to spreadsheet programs, greatly enhancing its appeal to both students and professionals.

The System 350 was powered by an Intel 8088 microprocessor, which operated at a speed of 4.77 MHz. This architecture provided sufficient processing power for its target applications, enabling users to execute tasks efficiently within the confines of its pre-DOS graphical interface.

Memory capacity was another defining aspect. The base model typically came with 64 KB of RAM, expandable up to 640 KB, allowing users to store data and run larger programs. Storage needs were met by a 5.25-inch floppy disk drive, which became a standard for software distribution in that era, supporting the storage of files and applications.

In terms of display, the System 350 typically featured a CGA-compatible monitor that supported a resolution of 640 x 200 pixels in color mode. This allowed users to operate graphical applications while still maintaining clarity and readability on the screen.

The machine was equipped with several expansion slots, facilitating upgrades and hardware enhancements, which included additional memory and even improved graphics capabilities. This expandability made the System 350 a flexible option for users looking to adapt their system to evolving technological needs.

Connectivity options were also notable, supporting connections to printers and modems. This capability empowered users to print documents and communicate electronically, establishing a foundational way for early personal computers to interface with other devices.

In summary, the Radio Shack System 350 was a pioneering personal computer featuring an MS-DOS operating system, powered by an Intel 8088 processor. Its expandable memory, floppy disk storage, CGA display, and connectivity options positioned it as an accessible and versatile tool for both educational and business environments. As technology continued to evolve, the System 350 played a vital role in the personal computing revolution of its time.
