Launched in 1994, the Quadra 630 would not only be released under the LC and Performa labels but would introduce a raft of features never seen before in the Macintosh world.


The Quadra series had been available since October 1991 and users had been more than happy to get their hands on the power of the Motorola 68040. In the shape of the Quadra 700 and 900, the cost of owning a Quadra had been far beyond the reach of many users (specifically home users) and while the Centris line (which used the 68LC040 – a 68040 without a dedicated floating point unit) had been available, it wasn't always what buyers wanted. The new Quadra 630 though was not only far cheaper, it also wasn't a 'cut-down' or 'yesterday's technology' machine.

Ever since the Macintosh had first sported a hard disk in the Mac SE or even the ability to add a hard drive in the Mac Plus, Apple had favoured the Small Computer Standard Interface (SCSI) system. SCSI was reliable and fast but it was also expensive compared to the far more widely adopted Integrated/Intelligent Drive Electronics (IDE) system and drive sizes tended to be smaller in terms of storage space. The IBM PC (and clones) tended to use the IDE mechanism; so, too, would the Quadra 630, making it the first Mac to do so. In itself this was a step forward in terms of cost-cutting but was curious as the machine still sported an optional SCSI CD-ROM drive and a full SCSI bus (complete with DB-25 external connection).

The change in drive technology wasn't the only 'first' that the 630 introduced, and its new low-profile case was specifically designed so that the the motherboard could be easily slid out and accessed – all a far cry from some of the seemingly impenetrable designs that came before it. The 630 was also the first Macintosh to include an optional video expansion system allowing users to add a TV tuner, video input, and video output (PAL and NTSC). The three sockets were all bespoke but the machine did come with a single extended LC PDS slot allowing more 'conventional' cards to be added, too.

Running at a very healthy 33 MHz, the Quadra 630 was a solid, if uninspiring, machine. Memory was limited to a single 72-pin DIMM slot (although the Performa 631 sported two slots) which allowed memory to be expanded to an adequate 36 MiB when a 32 MiB module was running alongside the 4 MiB of on board RAM (N.B. Apple certify the machine with modules up to 32 MiB but, in reality, the machine will happily accept 128 MiB modules, thus raising the RAM ceiling up to 132 MiB).

As well as being released under the Quadra name, the machine was also available as the Performa 630, and the LC 630. The Quadra, Performa, and LC branding were aimed at the business, home, and educational market, respectively. While effectively the same machine, the Performa and LC versions both shipped with lower cost/power 68LC040 CPUs – though still running at 33 MHz. As if all of these choices weren't enough, the LC version was also available with a factory fitted DOS card, which was cleverly attached directly to the CPU socket and PDS slot, thus leaving the communication and video slots free. This enabled users to run DOS and Windows without the need for purchasing an IBM compatible machine.
