The CASIO FX-501P and CASIO FX-502P were identical calculators except
for the amount of available program memory. The CASIO FX-502P is
the non-alphanumeric predecessor of the CASIO FX-602P.
I've never actually used this calculator. I obtained it by exchanging
it with a CASIO FX-601P I owned at the time with someone who preferred
alphanumeric above memory. This was during a summer job at Philips
Medical Systems in Best.
This calculator (as do many other CASIO scientific calculators) uses one and the same key for both the constant π as well as exponents. This works as follows. When you first enter digits, the "EXP"-key will enable you to enter the numbers exponent, otherwise it will enter the constant π.
