This specifications library provides the basic economic, technical, and physical characteristics of IBM, Hitachi, Amdahl, and many Comparex mainframes. This information includes memory capacity, channel capacity, processing power in MIPS and MSUs as well as the basic information needed to specify the required physical plant requirements.
The computer performance estimates we provide for IBM processors are based on IBM's own benchmark tests and our calculation. Ratings of IBM compatible processors are based on material provided from a number of sources, including the manufacturers.
The technical specifications are drawn from our collection of technical documents published by manufacturers.
The sale prices are drawn from our own surveys of the market at the time each system was first delivered; exceptions to this are noted on the page where they appear.
Maintenance prices are also those quoted at the time a system was first delivered; for updated maintenance costs, please contact the machine's manufacturer.
To obtain details on any of the mainframe families in the following list, just click on the appropriate linked text.
