The original TI-1500 uses a keyboard
layout with the [%] key on the left of
the [0] key.

The second version of the TI-1500
corrected this flaw and uses a more
convenient layout.

The third version of the TI-1500
kept the layout but changed the
readability of the display.

The first version of the TI-1500 makes 
use of 9 discrete LED-modules and a
magnifier lense glued on top of them.

The second version of the TI-1500 with 
the Opto-stick display manufactured by
Bowmar - actually a competitor of TI.

The final version of the TI-1500 with a 
standard LED-stick manufactured by TI
and a nice shaped bubble-lense stripe.
