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. |
