The Olivetti M280 is an 8286-based computer that runs at a Speedy 12 megahertz. It is the successor to the Olivetti M28, which operated at 8 megahertz. While both machines belong to the 80 series, the M280 offers an improved performance with its higher clock speed. In the following sections, we will take a closer look at the physical features and internal components of this vintage computer.

#3 Physical Features of Olivetti M280

The Olivetti M280 boasts a unique and distinctive design. Its exterior features a prominent "Olivetti M280" marking and an array of buttons and lights. The loudspeaker and green lighting add to its aesthetic appeal. However, upon closer inspection, there are signs of wear and damage. The casing shows rust, cracks, and missing buttons, indicating the need for some restoration work. Let's open up the case and explore further.

3.1 Exterior Design

The Olivetti M280 follows the signature design language of Olivetti, characterized by its distinctive grille pattern. This design element gives the computer a vintage appeal and sets it apart from other machines of its time. The 5.25-inch floppy drive is a standard feature, and based on previous knowledge of the Olivetti M28, we can assume that there is also a hard drive Present.

3.2 Rust and Damage

Upon closer inspection, the Olivetti M280 reveals signs of rust and damage. The top casing shows visible rust, which will require special treatment to restore its original condition. Additionally, there are areas of corrosion and visible wear on the exterior of the computer. These issues will need to be addressed during the restoration process.

3.3 Opening the Case

Opening the case of the Olivetti M280 reveals its internal components. However, the process is not as easy as expected, indicating the presence of rust inside the case. Further steps will be required to properly treat the rust and ensure the longevity of the computer.

#4 Internal Components

The Olivetti M280 houses various internal components that contribute to its functionality. Let's take a closer look at each of these components and their respective roles within the computer.

4.1 Network Card

One of the components we discovered inside the Olivetti M280 is a network card labeled "LCS 8834 Revision B2." This network card is unusual, as it does not bear the usual Olivetti markings. It features several switches for configuration, suggesting its role in networking capabilities. Further research is needed to determine its exact purpose and compatibility with modern networks.

4.2 Videographic Controller

Another component found inside the Olivetti M280 is a videographic controller. This controller, branded as "Paradise Geo4," provides the computer with graphics capabilities. With further exploration, we can assess its condition and determine if any repairs or replacements are necessary.

4.3 RAM

The Olivetti M280 is equipped with RAM, which is essential for the computer's performance. At this stage, we expect the RAM to have a capacity of 256 megabytes. However, a thorough inspection is required to confirm this assumption.

4.4 Floppy Disk and Hard Drive Controller

The Olivetti M280 features a combined floppy disk and hard drive controller. This controller plays a crucial role in managing data storage and retrieval. Additionally, it allows for the connection of external devices through its seven slots. In the case of the M280, two expansion cards have been installed, possibly for a monitor and an Ethernet controller.

#5 Cleaning and Maintenance

To ensure the Olivetti M280 operates at its optimal level, cleaning and maintenance are necessary. Let's explore the steps involved in cleaning and maintaining the various components of the computer.

5.1 Cleaning the Power Supply

The power supply is a critical component of any computer system. In the case of the Olivetti M280, its cleaning and maintenance are essential to ensure proper functionality. By using isopropyl alcohol (IPA), the power supply can be thoroughly cleaned and prepared for further testing.

5.2 Assembling the Power Supply

Once the power supply is clean, it must be reassembled and placed back into the computer casing. This step ensures that the power supply is securely connected and prevents any potential damage or accidents during testing.

5.3 Testing the Power Supply

With the power supply securely installed, it is important to test whether it is functioning correctly. By using a voltmeter, we can verify if the power supply is providing the correct voltages, such as the 5-volt and 12-volt outputs. This testing process ensures that the power supply is reliable and can support the overall functionality of the Olivetti M280.

#6 Future Plans for Restoration

The Olivetti M280 exhibits signs of wear and damage, necessitating restoration work. Here, we Outline the future plans for restoring the computer to its former glory.

6.1 Rust Removal and Repainting

The rust and corrosion visible on the Olivetti M280's exterior mandate a thorough cleaning process. To restore the computer's appearance, the rust will be removed through a process involving Glass blasting. Once the rust is eliminated, the exterior will be repainted to ensure a pristine finish.

6.2 Assessing and Repairing Internal Components

Alongside the exterior restoration, the internal components of the Olivetti M280 require assessment and repair where necessary. This involves examining the network card, videographic controller, RAM, and floppy disk and hard drive controller. Any faulty or damaged components will be identified and repaired or replaced accordingly.

6.3 Final Assembly and Running the Computer

Once all restoration work is complete, the Olivetti M280 will be reassembled and powered on. This final step will confirm the success of the restoration process and allow for the computer's functionality to be tested. We eagerly anticipate witnessing the Olivetti M280 in action, restored to its former glory.
