Calculation results are aligned to the left of the display.
When one enters a number, the display is first filled with zeroes, and these zeroes are replaced by the number entered from right to left.
The calculator does not understsand overflow. Multiplying 99999999 by another number displays some result, not the correct one.
Division by zero has a really strange outcome, it will display a random eight digit number, all periods lighting up and the third digit from the right will repeatedly count from 0 to 9.
There are three "SUPERLECTRON 8" calculators in my collection, the other two can be found here: SUPERLECTRON 8 and SUPERLECTRON 8.
