By the way, later Canon calculators are sometimes called "Palmtronic".
When I found this specimen on the Dutch auction website Marktplaats I couldn’t immediately make out what it was. At first I mistook it for a kind of label writer. Then I noticed its display which actually isn’t a display at all. This calculator is from a time when LED displays were too expensive and other affordable technologies did not yet exist.
Fortunately there are some very good resources on this early calculator.
The Vintage Calculators Web Museum has a detailed page here (link validated 2026-01-26)
Some other nice information can be found on History of Information here (link validated 2026-01-26)
This page (link validated 2026-01-26) on Computermuseum der Stuttgarter Informatik even has an (FTP) link to its service manual.
It will for ever be a secret when this calculator was used for the last time, but the last result it ever calculated is still "on display" as beging the value "96.5000".
I have yet to open up this calculator to remove its possibly leaking battery pack and am not sure if it still works. Still I found it important to include this early calculator in this museum.
