Apple II Language Card

This expansion card for the Apple II is designed to fit into slot 0. Known as the 'Language Card', it was released in 1979 and expanded a 48K Apple II into a full 64K memory computer. It did not remove the upper 16K of ROM, but the card contained 16K of RAM that was electronically parallel to the ROM. Using “soft switches” one could switch out the ROM and switch in RAM memory. This extra memory was used to load the Pascal disk system, and under DOS 3.2 and 3.3, to load into RAM the version of BASIC that was not in the ROM. This was a more flexible alternative to the Firmware Card, and opened the way to other languages beyond BASIC for Apple II users.
