The
Canon Palmtronic 10M, also known as LD-10M, 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).
If you feel familiar with this calculator you should compare it with the F-2 and F-6 scientific calculators.
Dismantling
the Palmtronic 10M reveals a single-chip calculator circuit based on the
TMS1000
Microcomputer family. The ZA0552 found inside the calculator seems to be a member
of the TMS1270 and is similar to the
calculator circuit of the TI-5200. This
chip was later used with the L1010 again.
Don't miss the later LD-10M 2 and LD-10M
3.
