Later G3 upgrade options offered by Sonnet and NewerTechnologies made use of the TAM's Level II Cache slot, which allow the computer to reach speeds of up to 500 MHz. It is the last Macintosh model able to boot and run System 7 natively.Įxpandability was offered via a 7-inch PCI slot and Apple Communication slot II for the addition of Ethernet.

The pre-installed operating system was a specialized version of Mac OS 7.6.1, which allowed control over those features.

The TAM also came with a remote control (standard with the Apple TV/FM Tuner card), but also featured buttons on the front panel that could control sound levels, CD playback, brightness, contrast, and TV mode. When not required, the keyboard could slide under the TAM's head unit, leaving the trackpad exposed for continued access. The trackpad could be detached from the keyboard if desired, with a small leather insert found underneath the keyboard ready to fill the gap. The TAM came with a unique 75 key ADB keyboard which featured leather palm-rests and a trackpad instead of a mouse. An Apple Engineer noted that the thick umbilical was intended to power a higher end CPU, however that option was ultimately curtailed, though the diameter of the umbilical remained.

Ensuring the connectors are free of dust/dirt has also been known to resolve the "buzz", though the buzz ultimately only affected a small percentage of machines. Inspections of units that received a repair by Apple due to the speaker buzz found one or more extra resistors had been installed in the umbilical. The umbilical connects via a multi-pin connector, which is a possible cause of the TAM's one major fault: the " speaker buzz". It had a vertically mounted 4x SCSI CD-ROM and an Apple floppy Superdrive, a 2GB ATA hard drive, a TV/FM tuner, an S-Video input card, and a custom-made Bose sound system including two "Jewel" speakers and a subwoofer built into the externally located power supply "base unit".Ī thick "umbilical" cable connects the base unit to the head unit, supplying both power, and communications for the subwoofer. The TAM featured a 250 MHz PowerPC 603e processor and 12.1" active matrix LCD powered by an ATI 3D Rage II video chipset with 2MB of VRAM capable of displaying up to 16-bit color at either 800圆00 or 640x480 pixels. Originally intended as a mainstream product, the marketing group turned it into a pricey special edition.
It was given a release date of March 20, 1997, with a retail price of £5,545 or €6,637. The TAM was announced almost 20 years to the day after Jobs and Wozniak incorporated the company, in January 1997 at MacWorld Expo, San Francisco. To reduce development time, many off-the-shelf components were used on the new computer's internals. However, the design team had already been working on several "dream" concepts, and soon settled on the most feasible of those: the (almost) "All-in-One" LCD-based design. The normal time-span to develop a new Macintosh computer was 18+ months, although available time was less. As this milestone arrived and came to the attention of Apple's then-current executives, the decision was made to release a limited edition Macintosh computer to celebrate-and so the "Spartacus" (or "Pomona", or "Smoke & Mirrors") project was born. Īpril 1, 1996, marked 20 years since the day that Steve Jobs, Steve Wozniak, and Ronald Wayne came together to form Apple Computer. The machine was a technological showcase of the day, boasting a number of features beyond simple computing, and with a price tag aimed at the "executive" market. The Twentieth Anniversary Macintosh (or "TAM") is a limited-edition personal computer released in 1997 to mark Apple's 20th birthday. Mac OS 7.6.1 (initial OS) – Mac OS 9.1 (final OS)
