Apple 820- logic boards

Apple logic boards are numbered 820-xxxx on older models and 820-xxxxx on newer ones, sometimes followed by a revision letter (820-2915-B). The number is printed on the board itself.

The A number on the bottom case (A1278, A1466, A2179) identifies the model, not the board. One A number can use several 820 boards across production years, so always search by the 820 number.

The catalog has 143 boards with Apple 820-xxxxx codes, mostly from Apple.
