Replacement for the ageing Quadra 700, the Centris (later Quadra) 650 might not have provided much of a speed boost but it did address the 700's biggest failing: expansion.

History

Along with the Quadra 900, the Quadra 700 had launched the flagship Quadra series in 1991. The new machines had put the power of the Motorola 68040 into the hands of users and they'd been very warmly received. Two years later and the pair were starting to look a little long in the tooth. The 950 had already been replaced by the Quadra 950 and, in February 1993, it was time for the 700 to drop off the product list.

Centris

When first released, the Quadra 700 had been one of Apple's top-of-the-range machines but that didn't mean that it wasn't without its problems. By re-using the case from the IIci the machine had no internal drive bays, which meant that there was no way for users to add the one device that was very quickly becoming a 'must have' — the CD-ROM drive. The 650 not only addressed this but also gave the old workhorse a bit of a shot in the arm at the same time.

Despite being initially launched under the Centris label, the 650 boasted a full-blown 68040 rather than the lower price/performance 68LC040 (which lacks the dedicated floating point unit) seen in the other Centris machines. (N.B. A limited number of the Centris machines did come fitted with the 68LC040 instead of the 68040. These machines also lacked on board Ethernet and came with only 4 MiB of on board RAM instead of 8 MiB.) Running at the same 25 MHz as the 700, the new machine might not have seemed like much of an improvement but by using interleaved 72-pin SIMMs, instead of 30-pin modules, users could see a 10% speed boost. The new and improved SCSI bus sped up disk access and the accelerated video made everything look great.

If this wasn't enough speed, users only had to wait eight months until the machine was rebranded as the Quadra 650. Everything was the same as before except that the machine was clocked at 33 MHz instead of 2 5MHz...and costed $300 less.

Where both versions of the machine excelled over the older 700 was in the field of expansion and connectivity. The older machine had lacked any sort of internal drive bay — aside from the pre-filled single hard drive and floppy bays — and while there had been two NuBus slots and a PDS slot, there hadn't been any on board Ethernet — which used up a precious NuBus slot if users felt the need to add a NIC. The 650 had a spare 5.25" drive bay — which could be pre-filled with an optional CD drive (N.B. The 650, along with the Quadra 800, were the first Macs that could be booted directly from CD) — three NuBus slots instead of two, and an optional AAUI Ethernet interface.

Having taken the case from the IIvi may have certainly given the 650 the expansion options that were so desperately needed but it also re-introduced one of the most loathed cases in the history of the Mac. The steel case was very symbolic of the IBM PC and seemed to lack the warmth and friendliness that encapsulated the Mac. As an added 'bonus' the sharp metal edges make working inside the 650 something of a health hazard with it being all too easy to slice a finger, hand or foot and cause blood to enter the case.
