This is definitely a title I’m going to enjoy using!
Once again, I’ve got more buckling sleeve Model M content but with an interesting twist this time around! The Apple Newton Keyboard (model X0044) turns out is a Lexmark keyboard design and is a derivative of the IBM ThinkPad 500 and various Lexmark Lexbook (IBM Model M6/M6-1) keyboard assemblies, something that may give both Apple and ThinkPad folk the shudders.
Included is a brief tour around the keyboard, explanation and evidence of how it’s related to the Model M family (via Model M6-1), comparison of two discovered revisions, and pointers on how you can convert one to USB (including pinout diagrams)!
