Launch
Apple introduced it on May 18, 1992 as the replacement for the Quadra 900, and it was sold until October 14, 1995, a long commercial life for the time. It raised the bus and the 68040 from 25 to 33 MHz in the same tower chassis. Dates and data: EveryMac; the introduction is also recorded in Apple Support and Apple’s Tech Info Library.
Marketing
The professional flagship: 33 MHz, five NuBus slots, sixteen SIMM sockets for up to 256 MB, and standard Ethernet. With launch prices of $8,500 to $9,600 in the US depending on configuration, it was the most expensive Mac of 1992. (EveryMac.)
Flaws and fixes
Apple documents no model-specific defects in the sources consulted. Limits that do appear in its spec sheet: 8 or 16 MB of standard RAM expandable to 256 MB via 16 30-pin SIMM slots (80 ns); a single display on the built-in video.
