The Canon Palmtronic 8M, also known as LD-8M 3, 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 2 sports the same functionality in a slightly smaller housing.
If you feel familiar with this calculator you should compare it with the Palmtronic 10M (LD-10M 2).
Dismantling a Palmtronic 8M is always a small surprise, some use a calculator circuit manufactured by NEC company, others use a Texas Instruments circuit. Don't miss the sibbling here.
The final edition of the Palmtronic 8M, called LD-8M
4, uses the Hitachi HD36264 single-chip calculator circuit of the LD-8M
Don't miss the LE-84 and LC-8M for a direct comparision.
The similar Palmtronic 8 missed the memory, view the LD-84. Later a much smaller calculator appeared with the LD-8Ms.
