jumper). A correspondant gave the following example:
which was on the list of those permitted in exams. No
programmable calculators were allowed.
A very similar, more expensive, programmable model had two
extra keys for programming where the cheaper version just had
blank metal.
My friend took his calculator apart (as you would) and lo and

the circuit board. So all he had to do was cut a hole in the
face. For exams he would pre-load the calculator with any
useful routines, put a sticker with his name on it over the
hole, and press the buttons through the sticker with a pen.
