3.Use pliers to squeeze down the tapping blade.

4.Close the insulated cover so it snaps.

MOUNTING THE MAIN MODULE

Select a location for the main module where it is completely concealed and difficult to access after installation. An ideal location is usually under and be- hind the vehicle’s dashboard on the firewall. Use two of the supplied wire ties to secure the main module under the dash.

INSTALLING THE STATUS INDICATOR

Use the supplied mounting bracket to hold the indicator or drill a hole in the dash. Follow these steps to install the indicator.

1.To use the supplied mounting bracket, use denatured alcohol to clean the surface and let it dry completely. Peel the backing off of one side of the double-sided tape and press it onto the bottom of the bracket. Then peel the adhesive backing from the other side of the tape and press the bracket onto the dash.

To mount the indicator in the dash, drill a 1/4-inch hole at the desired location. The surface should be less than 1/8-inch thick.

2.Press the supplied grommet into the mounting hole from the front of the surface.

RS-4000 specifications

The Radio Shack RS-4000 is an iconic piece of technology that embodies the spirit of innovation in the consumer electronics industry during the late 20th century. Launched in the 1980s, this personal computer made a significant impact on the home computing landscape, appealing to hobbyists, educators, and early computer enthusiasts alike.

One of the standout features of the RS-4000 was its affordability, which made technology accessible to a broader audience. The computer was powered by a Zilog Z80 microprocessor, a popular choice at the time due to its reliable performance and efficiency. With a clock speed of 4 MHz, the RS-4000 provided basic computing capabilities that were sufficient for word processing, simple programming, and educational software.

The RS-4000 came with 64 KB of RAM, expandable up to 256 KB, allowing users to enhance the system’s performance as their needs grew. For data storage, the computer utilized an external cassette tape interface, which was a common method for saving and loading programs during that period. This tape system was ultimately replaced as technology progressed, but it represented a significant step forward in personal computing.

Another notable aspect of the Radio Shack RS-4000 was its comprehensive range of input and output options. The machine featured basic keyboard input, a built-in speaker for sound output, and compatibility with various peripherals, including printers and modems. Additionally, it provided both video output to standard television sets and the option for users to connect external monitors, bringing versatility to the display options.

The RS-4000 supported a variety of programming languages, including BASIC, which allowed users to delve into programming and develop their software applications. This capability contributed to the rise of a generation of computer coders and technology enthusiasts who would go on to shape the digital future.

In summary, the Radio Shack RS-4000 was more than just a computer; it was a catalyst for creativity and innovation during the formative years of personal computing. With its user-friendly design, expandability, and a growing library of software, the RS-4000 played a crucial role in helping individuals understand and embrace the digital age. Although technology has advanced significantly since its release, the legacy of the RS-4000 remains in the hearts of those who experienced it, marking a pivotal moment in the evolution of personal computers.
