The
Canon Palmtronic 8Ms, also known as LD-8Ms, followed the LD-8M3
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.
The Palmtronic 8s used a similar
housing but lacks the memory.
