original TI-1500 was soon replaced with this revised
We noticed two major changes:
|• The [%] key found its place in the usual place instead
left from the  key.
• The expensive display made of 9 single 7-segment modules
borrowed from the SR-50 was replaced with a LED-stick
manufactured by Bowmar and known from the TI-2500B.
Within few month Texas Instruments started production of their own LED-sticks and the TI-1500 was changed again. Don't miss the 3rd design.
Texas Instruments manufactured the
TI-1500 in Italy for the European market, too.
