My IBM Enhanced Keyboard (the standard Model M) wiki page is functionally complete and got enough illustration! There are still a few variants left that I need to cover, but basically, all the common ones are present (plus, a unique and whacky Unicomp that supports a phone line at the end!)
Meanwhile, also added a small page about the IBM 1130 Computing System keyboard, the first IBM 029 keypunch based keyboard in my wiki!
