The
original TI-30 III received a minor redesign within
one year of its introduction:
In
addition to the ON/C key all keys of the upper row got small bumpers to prevent
unintentional keystrokes. Don't ask for the reason.
The
printed circuit board (PCB) of the TI-30 III used again the TP0456/CD4565
known from the TI-30 LCD.
Don't miss the TI-30 III assembled in Italy
sporting a completely different printed circuit board.
