The Canon "Palmtronic" 8Rs is a plain calculator of the seventies with
one nice peculiarity. The calculator does have a Memory function, but
there's only an "MR"/"MC"-key on the keyboard. It works as
follows, the "="-key also operates as an "M+"-key. Every
calculation result is automatically added to the calculator's memory.
There's also a Canon "Palmtronic" 8S which has a square root key instead of the "MR"/"MC"-key.
