This
Toshiba BC-1205B - introduced in 1973 - was far ahead the competition. Instead
the usual display with 8 digits or 10 digits resolution found in the LE-80
resp. Canon LE-10 this one sports a 12-digit
display assembled with red LED's (Light-Emitting Diodes).
The BC-1205B makes use of a chip set consisting of the Toshiba
T3125 and T3130 never found in any other calculator.
Even
the keyboard assembly looks unusual for such a small calculator. It uses a very
reliable construction with small magnets and Reed-contacts known from early
desktop calculators.
The Toshiba BC-0804B uses an almost identical housing
but sports a green Vacuum Fluorescent Display.
