[cctalk] Cursor keys and the Inverted T layout, Was: The magic smoke....

Cursor keys were notoriously unergonomic before the introduction of the inverted T layout present on the DEC LK-201, which became the industry standard keyboard layout after IBM copied it for the Model M. Basically every home microcomputer that had cursor keys, had them inline with each other in a very unintuitive layout. I imagine that DEC likely weren't the first to come up with the inverted T, even if they were the first to place it on it's own between the main QWERTY section and the number pad (which is also unlikely). Is anyone aware of earlier examples of the inverted T, or at least similar layouts to the LK201? Josh Rice
