The computer uses Complementary Metal-Oxide Semiconductor (CMOS) technology extensively to provide compact size, minimum weight, low power usage, and high reliability. This computer incorporates the following features and benefits: The computer is equipped with a Intel® Mobile Pentium® III processor, which incorporates a math co-processor and a 32 KB cache memory. The following processors are available: Intel® Mobile Pentium® III: 500 Mhz Other processor speeds may be introduced as they become available The processors have the following level 2 caches to maximize performance: Intel® Mobile Pentium® III 500 MHz: 256 KB There are two slots for memory modules, which come in two capacities: 64 and 128 megabytes of SD Random Access Memory (SD-RAM). The modules are 144-pin, SO Dual In-line Memory Modules (SO-DIMM) The computer provides 8 MB of RAM, 64-bit data path, for video display. The computer is powered by one rechargeable lithium-ion battery pack. The computer has two internal batteries: One backs up the computer’s special memory features and the other backs up the internal Real Time Clock (RTC) and calendar. An easy-to-use 85-key (United States) or 86-key (Europe) keyboard provides a numeric keypad overlay for fast numeric data entry or for cursor and page control. The computer’s keyboard supports software that uses a 101- or 102-key enhanced keyboard.
