It sounds to me like it is an Applesoft BASIC ROM card for the Apple II
(The original Apple II) computer, which only has Integer BASIC in RAM.
The II+ came with Applesoft already built in.

The switch on the back is used for switching from the ROM on the card
to the ROM on the motherboard and vice versa.

I don't think it will work in a IIe or a IIgs.
