Introduction

This tutorial provides a step-by-step guide on upgrading an IBM 5170, focusing on the challenges faced during a motherboard swap and the replacement of the VGA monitor. Whether you're an enthusiast or a beginner, this guide will help you navigate the potential pitfalls and ensure a successful upgrade.

Step 1: Gather Necessary Tools and Materials

Before starting the upgrade, gather the following tools and materials:

• Deoxit D5 for cleaning connections
• O-Ring Pick Set for lifting chips
• Logic Probe for testing
• Desoldering Iron for removing components
• Oscilloscope for diagnostics
• Soldering Iron (e.g., TS100) for soldering tasks
• Multimeter for electrical measurements
• Magnetic Screw Holder to keep screws organized
• Universal ZIP sockets for chip testing

Practical Tips

• Ensure your workspace is clean and well-lit.
• Organize your tools to avoid losing any small parts.

Step 2: Remove the Old Motherboard

1. Power down the IBM 5170 and unplug all cables.
2. Open the case by unscrewing the side panels.
3. Locate the motherboard and take note of all connections.
4. Carefully disconnect all cables and peripheral devices.
5. Unscrew the motherboard from its standoffs and gently lift it out.

Common Pitfalls

• Be careful not to force any connectors; they may be fragile.
• Keep track of screws and connectors to prevent losing them.

Step 3: Clean the Motherboard and Connectors

1. Use Deoxit D5 to clean the contacts on the motherboard.
2. Inspect for any corrosion or dirt on connectors.
3. Allow the cleaner to dry before proceeding.

Practical Advice

• Cleaning can prevent poor connections and improve performance.
• Consider using a magnifying glass to inspect small components.

Step 4: Install the New Motherboard

1. Align the new motherboard with the standoffs in the case.
2. Secure it with screws.
3. Reconnect all cables and peripheral devices according to your notes from Step 2.

Tips for Success

• Ensure all connectors are seated properly.
• Double-check that no cables are pinched or obstructed.

Step 5: Replace the VGA Monitor

1. Disconnect the old monitor by unplugging it from both the power source and the computer.
2. Position the new VGA monitor in place.
3. Connect the monitor to the video output on the new motherboard.
4. Plug in the monitor's power supply.

Troubleshooting

• If the monitor does not display anything, check all connections and ensure the motherboard is functioning properly.

Step 6: Test the System

1. Power on the IBM 5170.
2. Observe the boot process for any errors or unusual behavior.
3. If issues arise, use the Logic Probe and Multimeter for diagnostics.

Key Considerations

• Be patient; troubleshooting can take time.
• Refer to the original motherboard documentation for error codes.

Conclusion

Successfully upgrading an IBM 5170 involves careful preparation, methodical execution, and troubleshooting. By following these steps, you can navigate the challenges that often accompany such upgrades. Once complete, consider exploring further enhancements, such as BIOS improvements or overclocking, to maximize your retro computing experience.
