I was just looking at Unicomp's web site. They have a listing for a "Sun Unix Space Saver Keyboard." It's a 105-key layout with a short spacebar, Capslock, Alt, and Diamond on the left, Diamond, Alt-Graph, Compose, and Control on the right. That is, Control and Capslock are swapped, with Control up by the "A" key.
The other interesting thing is the usual Backspace key spot is filled with two 1u keys, "|\" and "~`". The 1.5u key over the ANSI-style Enter is Backspace... which for some reason is white instead of gray.
I'm mentioning this here because this is where I first encountered "move the Backspace key down to above Enter". I didn't realize there were actual production keyboards made that way.
