Amber 64: Mining Hacker History from Commodore 64 Discs
The Amber 64 project applies modern digital forensic techniques to analyze over 500,000 Commodore 64 floppy discs, creating a searchable index of vintage computing artifacts that preserves the digital history of early hacker culture. The project collected discs from various archival sources, considering each disc unique even with single-bit differences, and uses Elasticsearch to enable rapid searching across this massive collection of computing history.
Key Technical Aspects
- Disc Collection: Over 500,000 unique Commodore 64 disc images compiled from online archives, preservation projects, and personal collections—with uniqueness determined by hash differences
- Advanced Forensics: Modern forensic techniques including file system analysis, metadata parsing, and deleted file recovery applied to 35-40 year old floppy discs
- Technical Innovation: The project developed specialized parsing techniques to handle the Commodore 1541 disk drive's unique architecture, which was essentially a separate computer with its own processor and RAM
- Encoding Challenges: Addressed the complexity of the Commodore 64's non-standard text encodings, which could use multiple possible character sets per disc, sometimes with no clear indication of which was intended
Historical Context
The Commodore 64, produced from 1982 to 1994, was a foundational computer for early hackers and digital pioneers. During an era before widespread internet access, users engaged in hacking, phone phreaking, software piracy, and connected via bulletin board systems (BBS). The project preserves artifacts from this formative period when computing culture was largely defined by software sharing, technical exploration, and underground communities.
Notable Discoveries
- Lost software including previously unarchived games like "Asteroid Miner"
- BBS conversation logs capturing real-time interactions from early online communitie

You can bet you're behind that I am here for this talk. I actually have known a little bit more about this talk for a long time while Wes was uh working on this. Uh Wes is a wonderful friend of everybody's here. uh Wes Wes and I work in similar fields in digital forensics and are fairly casual about things and I think this is going to be a casual and fun talk that is just going to be a blast that you you bet your ass I'm going to stay around for. So everybody give Wes a big round of applause and let's have a good time. >> Thank you, man. >> Thank you so much. >> Thank you everybody. I appreciate it. We're just going to hop right into this. So this is Amber 64. We're mining hacker history from over half a million Commodore 64 discs. It's all the ones I could find. Uh I'm a senior cyber fell…
