I have been working on a new layout for the various sections for a while and the changes have now gone live. It made more sense to order the information by type rather than period to keep things clear. Hopefully this gives some of the stuff more exposure since some pages were clearly more visited than others.
With this comes a large amount of minor edits and quite a bit of new stuff here and there: mainly regarding keyboards, the late 1970s and post-KC 1980s as well as early 1990s. Let me know if you find any errors, typos or missing info you can help out with – and happy browsing!
