This
TI-603D is an unique calculator in TI's long line of so-called "four
bangers". At first glance it looks like a common TI-1766
III but we notice the uncommon [DAY] key in the upper row of the keyboard.
This key allows the easy calculation of the "Day of the Week".
EXAMPLE: To obtain the week day for June 4, 1960 press:
[ON/C][DAY] 04 06 60 [DAY]. The display indicates that the curator of this
website was born at a Saturday.
The TI-603D is Y2K compatible, in the 21st century the year is
entered as a 4-digit number.
The
day-month-year entry indicates that the TI-603D was sold only on the European
market. Dismantling the calculator reveals a small surprise, the printed circuit
board (PCB) is labeled with TI-1763. Up to now this number was unknown...
The predecessor TI-603 has nothing in common with the
TI-603D. Nevertheless showed the box of the TI-603D a flaw.
