MB10/MB15 variant

76-key keyboard assembly for the Lexmark Lexbook MB10 and MB15 DOS subnotebook laptops. It has an integrated "mouse-key" in the bottom-right corner that acts as a joystick-like pointing device and two mouse buttons placed in between the left Ctrl and Alt keys. Its physical layout is derived from the IBM ThinkPad 500-series Keyboard Assembly but makes fewer layout compromises at the expense of fewer total keys. It has an overlay numeric keypad with vibrant blue legends.
