OMRON 8PM Made in Japan - Computer

Plain calculator with basic functions, percentages, square roots and memory.

Its battery compartment is not at the bottom but at the front, on top.

Another peculiarity, the minus sign to designate a negative number is not shown using the center segment but using the top segment. That is probably done to not conflict with the used sign for a non-zero value in memory, a small "u".

It has a fluorescent display, and numbers are displayed starting on the left.

The calculator will be packed carefully.
