Hi, have an old (‘86) FX-750P and after changing batteries of the calculator and Ram Card it keeps showing the error message $$$.
Manual says that error is because Ram card is not present in Slot 0.
Help please.

This calculator needs to work at least one ramcard in slot 0.

If you have it but the calculator still says that, check the battery of the ramcard.

Also would help to blow the slot 0 dock and clean with alcohol the ramcard contacts.
