Full Specifications

The fifth machine in Apple's line of original Macintosh all-in-one (AIO) machines, the SE/30 was a massive leap forward in terms of power and expansion.


Ever since the launch of the original Macintosh in 1984, all of Apple's all-in-one machines had shared many common aspects. They all had an integrated 1-bit 9" screen, they all used the venerable 68000 processor and they all ran at 8 MHz. In 1984 8 MHz had been fast but, in 1989, 8 MHz was practically criminal.

With the release of the Macintosh II, Apple had hoped that the Macintosh SE would be seen as the low-end cousin of the new desktop machine. While it was an admirable little machine, the SE was definitely starting to show how limited the original Macintosh had become. It was time for a speed was time for the SE/30.

The SE/30 was a massive leap forward for the all-in-one Mac line. The original 68000 CPU, running at 8 MHz, was replaced with the shiny new Motorola 68030 running at a blistering 16 MHz. Not only did this give the machine a speed boost but the new CPU allowed for 32-bit addressing, thus enabling the little SE/30 to blast through the 4 MiB RAM ceiling on the SE and go all the way up to 128 MiB of RAM — even if Apple never certified it with the necessary 16 MiB SIMMs.(N.B. The SE/30's ROM was considered 'dirty', like the IIx and IIcx ROMs, only allowing it to run in 24-bit mode unless the MODE32 system extension was applied. Apple promised to deliver an updated ROM but never actually shipped replacements, instead opting for MODE32). In addition to all of this, the SE/30 was fitted with a dedicated floating point unit (FPU) in the shape of the 68882 — another speed boost.

All of this would have been enough to satiate most Mac fans, yet Apple threw seemingly everything at the little machine. The expansion slot that first saw the light of day in the SE was replaced with a more powerful PDS slot (the same as that used in the IIsi, but running at a different speed — for this reason extra caution should be applied when trying to use expansion cards from one machine in the other), the audio system went stereo and, despite its diminutive appearance, the SE/30 was a powerhouse of a machine often employed as a file or mail server.
