introduced in 1979 with the stylish Canola L-3 a very capable battery operated
desktop calculator with a large 12-digit Vacuum Fluorescent Display (VFD) based
on Hitachi's HD38401A single-chip calculator circuit.
Dismantling the featured Canon Canola L-3 small desktop calculator manufactured in 1980 in Japan reveals a very cost-effective design using a rather small single-side printed circuit board (PCB) dominated by a large 12-digit VF-Display hiding the Hitachi HD38401A chip and connected to a large keyboard assembly and powered by 4 AA-sized alkaline batteries or an optional rechargeable battery pack.
About 10 years later the Canola L-20 II continued the design approach of this Canola L-3 and reused its Hitachi chip.
