A seventh(?) version exists "MAXI SWITCH MEXICO 08-23-96", another "05-28-97". At first glance the only obvious difference to previous models is that the PS/2 plug is bright orange. The real significance of this unit is the recognition of the extra Windows keys added. Rather than retool the unit to allow the addition of the three extra keys and therefore altering the standard layout around the space bar, a simple electronic change was made to the decoder and some keys relabeled. Using an extended IBM Model M as a guide, to the left of the space are three keys: |CTRL |* |ALT | which are relabeled |CTRL |WIN|ALT | and on the right of the space bar, |ALT | * |CTRL | are labeled |ALT |WIN|MENU |. How many people remapped the MS keys to reproduce the right-hand CTRL key is unknown.
