Notes: This is a very thin calculator glued into a foldable sleeve. It is a plain calculator with percentages, the square root, and memory.

The right part contains a name tag and a table for unit conversions, named "CONVERSION METRIQUE" on one side and "METRIC CONVERSION" on the other.

One would expect the contents of the memory to get lost when there is not enough light. This calculator keeps its memory for a couple of minutes, even when the sleeve is folded shut. Eventually its contents is lost.

There is not a lot of information on this calculator when you Google it. At the time of this writing (2023), the only other calculator site listing it is, see this page (link valid 2023-05-15).
