The Canon Canola L1010 is another calculator based on the TMS1000 Microcomputer family. The ZA0552 found inside the L1010 seems to be a member of the TMS1270 Product Family and is similar to the calculator circuit of the TI-5200. We know the ZA0552 already from the Palmtronic LD-10M introduced in 1975. 

An identical housing was used with the Canola L812 sporting a smaller 8-digit Vacuum Fluorescent Display (VFD).

Dismantling the featured Canola L1010 calculator manufactured in January 19778 reveals a very cost effective design using a single-sided printed circuit board (PCB) centered around the ZA0552 single-chip calculator circuit connected to an 11-digit VFD, a keyboard assembly using another single-sided PCB and powered by 4 AA-sized alkaline batteries

The ZA0552 single-chip calculator circuit is not yet explored but we will enable our DCM-50A Platform to allow the Characterization of Single-Chip Calculator Circuits of TMS1200/TMS1270 devices soon.

Canon replaced early in 1978 both the Canola L812 and L1010 with the L813 and L1011 models sporting a much sleeker design and allowing to replace the batteries from the top.

Don't miss the LC1014 using the early yellow LCD display.
