The
Canon Palmtronic 8s, also known as LD-8s, followed the LD-84
and uses a much smaller housing similar to the LC-8M
with a yellow LC-Display.
The
engineers at Canon used some tricks to achieve an overall thickness of only 0.55".
The calculator chip, a TMS1042 based on the TMS1000
Microcomputer family, is soldered with bended pins on the printed circuit
board and the green VF-Display uses straight pins.
Funny to know that the Palmtronic 8s sports a hidden memory, view the Palmtronic 8Ms using the same calculator chip.
Don't miss the TI-2550 III introducing the TMS1043 calculator chip runing from just one AA-sized NiCd battery.
