The keyboard part number database is one of the largest repositories of keyboard data on the internet. It's an ever-growing collection of known IBM, Lexmark, Unicomp, Toshiba, and Lenovo branded keyboard part numbers and specific design data for each. The database is built upon data collected from official IBM and co documents and manuals, past eBay and other auction website listings, other repositories like deskthority wiki, and community submissions.
Articles are my research, teardown and review type publications. The contents included on these pages are a mixture of known facts, observations I made, and my opinion on devices or topics in question.
Topics of interest are pure knowledge listings and articles for a specific topic like common questions, jargon-busting, plug and internal connections, notable external sites and pages, and recognised distinct keyboard types. The vast majority of these pages are purely factual with little opinion mixed in.
These guides are tutorial pieces designed to help with a particular situation, desire or problem. The focus is generally niché issues not widely described or solved elsewhere.
Gists are my looser and more opinion-based articles written without the grandeur of my proper articles above. Whilst still on the topic of keyboards and may still have factual merit inside, the specific topics of discussion are likely less clear-cut and people will have many differing opinions.
