Description

Performa 631CD Logic Board – 820-0624-A, 661-0158, 661-0189, 661-1114. This board has a 33MHz 68LC040 processor and 4MB memory module. The 631CD has a second memory slot! This logic board assembly just slides into place and all cables come to the board through the back plane connector inside the case.

Of course this logic board assembly will also slide right into the following models:

LC 630, Performa 630, 630CD, 635CD, 636, 636CD, 637CD, 638CD, 640CD, and I believe into a Quadra 630, Performa 6200 or 6300 should you decide to downgrade.
