Macintosh Performa 631CD - Revision history

Josh: Apple Service Source: case width and depth were transposed across the 630 family (Apple: 16.5 in W x 12.6 in D); sound is 8-bit MONO input and 8-bit stereo output (16-bit only in CD mode), not 16-bit stereo in and out; added Apple's 45 W supply rating, 1 MB ROM, the two logic-board SIMM variants 661-0158 (36 MB) and 661-1114 (52 MB), the no-internal-SCSI statement and the slot pinouts; recorded that Apple's own volume misprints maximum power as 5 W
