More about this type of keyboard...

The 1984-debuting IBM Wheelwriters 3 and 5 and IBM Quietwriter 7 were the first vessels for membrane buckling spring keyboard assemblies. Unlike the Model F's limited typewriter adoption, what would become the Model M would be featured on IBM and Lexmark Wheelwriters until their discontinuation in 1993. IBM Wheelwriter layouts were vaguely PC-like, with a mix of T-nav arrow keys, one or two columns of left-side function keys, and occasionally even a numerical keypad being found on various models depending on their market segment. The common feature amongst all of them was a split spacebar, with the smaller "Code" key being an additional modifier for accessing functions throughout the keyboard.
