The Macintosh Quadra 630 (Codenames: "Crusader", "Show Biz", "Show & Tell"; also sold with minor variations as the Macintosh LC 630 in the educational market and as the Macintosh Performa 630 in the consumer market) is a personal computer that is a part of Apple Computer's Quadra series of Macintosh computers. It was introduced in July 1994, replacing the Quadra 610, and was discontinued in October 1995 with no direct replacement - however, the Power Macintosh 6200 and its Performa versions took a very similar position in Apple's product lineup later, and continued using the new case introduced with the 630.

The 630 was the last Quadra Macintosh introduced, though the earlier 950 remained available longer. A big change compared to previous Macintosh models was the choice of hard drive interface: cheaper, but slower IDE drives were used instead of SCSI for the first time. SCSI ports were still available on the machines, and were in fact used for the CD-ROM (if one was installed), but they used an older controller that was much slower than the ones used in higher-end Macs of the time ^[1].

[edit] Variants

The 630 was available in a confusing number of configurations, especially in the Performa variants (which had slightly different model numbers). The Quadra 630 featured an 68040 processor, 4 MB of RAM, a 250 MB hard disk and a CD-ROM drive; the LC 630 was essentially identical, but had the FPU-less 68LC040 processor. The LC 630 DOS compatible added an additional 486DX2 processor at 66 MHz and dedicated RAM on a Processor Direct Slot card to the LC 630. The Performa versions were:

630 - The LC 630, but without the CD-ROM drive
630CD - Identical to the LC 630
630CD DOS compatible - Identical to the LC 630 DOS compatible
631CD - Like the 630CD, but with an additional RAM slot (for a total of two) on the motherboard, 8 MB RAM, 500 MB hard disk and sold bundled with a monitor
635CD - The 630CD, but with 5 MB RAM, bundled with a monitor and a modem
636 - The 635CD without the monitor and CD-ROM, but with 8 MB of RAM and the 500 MB hard disk
636CD - The 636 with a CD-ROM
637CD - The 636CD with the monitor, but only a 350 MB hard disk
638CD - The 637CD without the monitor, but a TV/video in card instead
640CD DOS compatible - The 631CD with a modem and the 630CD DOS compatible's 486 processor card
