TheeMac (short foreducation Mac) is a discontinuedall-in-oneMac desktop computer that was produced and designed byApple Computer. Released in 2002, it was originally aimed at theeducation market but was later made available as a cheapermass-market alternative to Apple's"Sunflower" iMac G4. The eMac was pulled from retail on October 12, 2005, and was again sold exclusively to educational institutions thereafter. It was discontinued by Apple on July 5, 2006, and replaced by a cheaper, low-endIntel iMac that, like the eMac, was exclusively sold to educational institutions.

The eMac design closely resembles theSnow iMac G3, though the eMac was only available in white, slightly larger in size, did not include a carry handle, and was heavier than the preceding G3, weighing 50 lb (23 kg). The unique shape of the computer was also similar to Apple's lastCRT-based 17-inchStudio Display, released in 2000 (the last standalone CRT monitor Apple made). The Apple eMac features aPowerPC 7450 (G4e) processor that is significantly faster than the previous-generationPowerPC 750 (G3) processor, as well as a 17-inch flat CRTdisplay which was less expensive and more rugged for the education market, making it a similar-performing alternative to the more premium iMac G4 with itsLCD.

Background

[edit]

In 1998, Apple released theiMac G3, anall-in-one computer built around acathode-ray tube display. The iMac was a major success for Apple, selling more than five million units; it also sold for as low as US$799, making it the most affordable Mac model Apple offered. In January 2002, Apple announced a successor to the iMac G3, theiMac G4. This iMac was built around a floating flat-panel display, and started at a higher price than the previous generation. While a few models of the iMac G3 remained at lower price points, they lacked power for educational tasks like video. Education customers made up nearly a quarter of Apple's sales,[1] and with Windows-based computers eating into Apple's market share of the sector, Apple consulted with educators to build a cheaper G4-powered successor for the price-conscious market.[2]

Apple announced the eMac on April 29, 2002,[3] to be sold only to education markets. Apple had previously created education-only computer models, including the iMac predecessorPower Macintosh G3 All-In-One. The machine's CRT screen made it cheaper than the iMac G4 (the most expensive configuration was still cheaper than the cheapest iMac G4), and its bulk was intended to make it more resilient to wear and tear in a school setting than the fragile hinge and flat screen of the iMac.

Design

[edit]

The eMac has a substantially similar design to the iMac G3, but features a larger 17-inch (430 mm) (16-inch viewable) flat-screenCRT monitor. The larger screen has 40 percent more viewing area than the iMac.[2] Thanks to the short-necked CRT, it takes up the same space as the iMac—in fact, it is a few millimeters shorter–but also is heavier, at 50 pounds (23 kg). The computer is powered by a PowerPC G4 processor much faster than the G3-powered iMacs. The machine's serial number and networking identification are printed on the front of the computer behind the optical drive door, intended to make it easier for schools to track purchases. RAM can be upgraded through a service hatch at the bottom of the computer. Apple sold a separate acrylic tilt-and-swivel stand to enable changing the viewing angle of the screen.[4]

Release

[edit]

After demand from consumers, Apple announced on June 4, 2002 that the eMac would be available through general retail.[5] Regular consumers did not get the same prices and configuration options as education customers; for example, education buyers could get a model without a modem.[6]

The eMac generally catered to the mass market, eventually taking over the entry-level (previously held by the iMac G3) Macintosh from 2003 to 2005, while the iMac G4 was positioned as a premium offering throughout the lifetime of the eMac line.[7] The eMac generally offered similar performance and features to the iMac G4 while they were sold side by side. The eMac was gradually supplanted by theiMac G5 in 2005 to 2006.

In October 2003, 800 MHz model was eliminated as a standard configuration and the 1 GHz model was brought down in price. This revision was the last in the line to officially run Apple's OS 9 operating system natively.

The next revision to the eMac line came in April 2004, withDDR SDRAM, a faster processor running at 1.25 GHz, and a betterATIRadeon 9200 video chipset. The most recent revision came in May 2005, with an even faster CPU running at 1.42 GHz,Radeon 9600 graphics, and larger standardhard disk.

On October 12, 2005, Apple once again restricted sales of the eMac to educational institutions and returned to its "E is for Education" marketing plan that had been attached to the product from the original restriction to education buyers. The company re-implemented this restrictive measure for unspecified reasons. Some analysts believe Apple wanted to force the general public to purchase the more expensiveMac Mini or iMac which had higher profit margins. Also, the eMac was the only CRT display product left in Apple's lineup, which made it somewhat bulky compared to new offerings which had compact form factors due to their LCD screens. The falling cost of LCD displays would also gradually bring down the prices of theiMac G5. However, the eMac was still available for sale to the general public through some third-party retailer websites.

On July 5, 2006, the entire eMac line was discontinued. An "educational configuration" of the iMac Core Duo was introduced that same day, which had a Combo drive rather than a SuperDrive and a smaller 80 GB hard disk.

Early eMac models natively bootMac OS 9.2.2 andMac OS X beginning withOS X 10.1.4, while later models only officially boot Mac OS X. 1 GHz and faster models cannot boot OS 9, while eMacs slower than 1 GHz do not officially support10.5 (requirements are an 867 MHz G4 with 512 MB RAM).

Reception

[edit]

The eMac was generally well-received.Macworld'sJason Snell wrote that the eMac served as a worthy successor to the iMac G3.[8] Criticism of the initial release version was that the low amount of installed RAM (128 MB) was not sufficient for Mac OS X.[9] The eMac was as easy to setup and had performance comparable to a similarly-equippediMac G4, making the eMac the most affordable point of entry with a Power PC G4 processor and DVD-recording.[10]

Technical problems

[edit]

A number of early eMac machines have suffered from what was known as "Raster Shift", a phenomenon where the bottom third or half of the screen goes black, with the rest of image shifting upward and beyond the top boundary of the display. Serious static also accompanies the problem, rendering the viewable part of the screen virtually useless. In response to the problem, Apple offered a solution which involved the replacement of the video cable inside the eMac's case.[11][12]Certain models of eMac also suffered fromcapacitor plague, that caused video distortion or the computer to lock up.[13] Apple responded to these issues by implementing a warranty extension program.[14]

Technical specifications

[edit]

All are standard configurations from Apple unless otherwise noted.

According to Apple, all of these models are obsolete.[a][15]
