Template:Mac specs The Macintosh SE/30 is a personal computer that was designed, manufactured and sold by Apple Computer, Inc. from 1989 until 1991. It was the fastest and most expandable of the original black-and-white compact Macintosh series.

The SE/30 is essentially a Macintosh IIx in the same case as the Macintosh SE, with a black-and-white monitor and a single PDS slot (rather than the NuBus slots of the IIx) which supported third-party accelerators, network cards, or a display adapter. Although officially only able to support 8 MB, the SE/30 could expand up to 128 MB of RAM, and included a 40 or 80 MB hard drive. It was also the first compact Mac to include a 1.44 MB high density floppy disk drive as standard (late versions of the SE had one, but earlier versions did not). Conversion sets were sold to convert a regular SE to a SE/30. The SE would then have the exact same specs as an SE/30, with the difference only in the floppy drive if the SE had a 800k drive. The set included a new front to replace the original SE front with that of an SE/30.

Apple had indicated the presence of a 68030 processor by adding the letter "x" to a model's name, but when the Macintosh SE was updated to the 68030, this posed an awkward problem, as Apple was not willing to name their new computer the "Macintosh SEx". Thus, "SE/30" was the name chosen. Internally, code names like Green Jade and Fafnir were used.[citation needed]

UpgradesEdit

Although sold as a 32-bit computer, the SE/30 ROM, like the IIx ROM, included some 24-bit code, rendering the ROM "dirty". This limited the actual amount of memory that could be accessed to just 16 MB. The solution was to use a program called MODE32 which enabled access to the extra memory (if installed). Alternatively it has been found that replacing the ROM SIMM with one from a Mac IIsi or Mac IIfx makes the SE/30 32-bit "clean" and thereby enables use of up to 128 MB RAM.[citation needed]

With some software hacks and the correct processor upgrade card, it also becomes possible to run OS 8.0 or OS 8.1, whereas without one, the SE/30 is limited to a maximum Mac OS version of 7.6.1 (only if you have a 32-bit clean upgrade), the last non-68040 version of the classic Mac OS.

Additionally, the SE/30 is able to run A/UX, Apple's older version of a Unix that was able to run Macintosh programs.

Though there was no official upgrade path for the SE/30, several third party processor upgrades were available, specifically a 68040 upgrade made it possible to run Mac OS 8.1, which kept the SE/30 relevant and productive for many more years than it would have otherwise been.

This machine was followed in 1991 by the Macintosh Classic II, a machine which was only 60% as fast as the SE/30, supported no more than 10 MB of memory, and lacked an internal expansion slot. Apple at this time was de-emphasizing the compact, all-in-one nature of the Macintosh in favor of a more expandable, PC-like system architecture as seen in the Macintosh II and Quadra series.

Popular cultureEdit

Template:Trivia In the NBC TV series Seinfeld, Jerry has an SE/30 sitting on his desk during the first seasons. This would be the first of many Macs to share the desk, including a PowerBook Duo and a Twentieth Anniversary Macintosh. Template:Timeline of compact Macintosh models
