The Canon Palmtronic 8Rs, also known as LD-8Rs, followed the LD-84 and uses a much smaller housing similar to the LC-8M with a yellow LC-Display.
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.
Interesting to know that even the Palmtronic 8s and Palmtronic 8Ms make use of the the TMS1042 calculator chip, despite their different specifications:
