Retrogamer Gen X takes a close look at the Backbit Chip Tester, a compact yet powerful device for diagnosing vintage chips. Whether you work with the Commodore 64, Atari 8-bit, Amiga, or other classic hardware, this tool helps identify faulty integrated circuits quickly and accurately.
The Backbit Chip Tester Pro V2 supports a wide range of ICs, making it ideal for enthusiasts who want to repair or restore old systems without guesswork.
Real-Time Testing and Firmware Upgrade
The video starts with a step-by-step firmware update to version 3.75. The process is simple—just copy the update to an SD card and insert it into the tester. Within seconds, the update is complete.
Next, the host runs real-world tests on several logic chips. Some are known to work, others are confirmed bad. The tester correctly identifies the failed chips, including LS logic gates and a hex driver.
Rare Chips and In-Circuit Testing
The video also explores the testing of a problematic Atari ANTIC chip. Though the chip passes, the issue turns out to be rare and not easily detectable with standard methods. Even so, the tester helps isolate the fault quickly.
The Backbit Chip Tester also supports in-circuit testing using chip clips and jumper wires. This allows you to check chips without removing them from the board—perfect for troubleshooting stubborn faults.
Constant Updates and Excellent Support
The tool’s chip database is always growing. If a specific chip isn’t supported, you can send the datasheet to Evie Salmon, the creator. She often adds new chips within days and pushes updates through firmware releases.
This makes the tester incredibly flexible, especially for rare or obscure components.
Is It Worth the Price?
At $200, the Backbit Chip Tester sits between budget options and high-end professional testers. While cheaper models exist, they often lack compatibility or features. Higher-end testers can cost over $400.
Considering its growing support, strong community, and responsive developer, this tester offers solid value for DIY repair fans.
Final Thoughts
If you’re restoring retro consoles or computers, the Backbit Chip Tester can save time and money. It removes the frustration of guesswork and replaces it with reliable diagnostics. With excellent support and frequent updates, this tool deserves a place on your bench.
