TOPIC
Power Computing provided the information in this article and it was deemed accurate as of 14 November 1997. Apple Computer, Inc. is not responsible for its content. This article is being provided as is and will not be updated in the future.
This article contains the technical specifications for the PowerTower Pro 180, 200, 225, and 250.
DISCUSSION
The is the first super high end machine that Power Computing has released. This is the first PC on any platform to ship at 225Mhz and its technology is dual processor capable. The PowerTower Pro is the most upgradeable machine yet as it offers six PCI bus expansion bays, eight RAM memory slots, and seven internal drive bays.
It is based on Apple's Tsunami main logic board design and the Power Macintosh 9500 is its equivalent. Even though the underlying technology is the Tsunami architecture, Power has made a few modifications to augment its functionality.
