The
Canon Palmtronic 8M, also known as LD-8M 4, is one of the successors of the
LE-series. Compared to the original LE-series using a red LED-Display (Light Emitting Diodes) the later LD-series sports the green
VF-Display
(Vacuum Fluorescent) and the LC-series either yellow of grey LC-Displays (Liquid-Crystal).
The predecessor called LD-8M 3 sports the same
functionality in a housing with a different design.
Dismantling
a Palmtronic 8M is always a small surprise, some use a calculator circuit
manufactured by NEC company, others use a Texas Instruments or Hitachi circuit.
This LD-8M 4, manufactured early in 1976, uses again the
Hitachi HD36264 single-chip calculator circuit known from the previous LD-8M
2.
