Features
The Toshiba T200/T200CS Pen Computer uses extensive Large Scale Integration (LSI), and
Complementary Metal-Oxide Semiconductor (CMOS) technology to provide minimum size
and weight, low power usage and high reliability. These computers include the following:
Microprocessor
The T200/T200CS uses an SL Enhanced Intel 486DX2-40 microprocessor that
operates at 40 MHz and 3.3 volts.
Math co-processor
The T200/T200CS has a math co-processor stored in the i486DX2 microprocessor.
Cache memory
The T200/T200CS has an 8 KB cache memory stored in the i486DX2 microprocessor.
Disk storage
The T200/T200CS has an internal 1.8-inch IDE 80 Megabyte (MB) Hard Disk Drive
(HDD).
Memory
The T200/T200CS comes standard with 4 MB of CMOS RAM. This includes 640
KB of conventional memory and 3,328 KB of extended memory, which can be utilized
as expanded memory compatible with Lotus/Intel/Microsoft Expanded Memory
Specifications (LIM-EMS).
Display screen
The T200 has a 9.5-inch high resolution monochrome Liquid Crystal Display (LCD)
which displays 640x480 pixels with a 16-level gray scale, and an electromagnetic
derivative tablet (transreflective).
The T200CS has a 9.5-inch high resolution Supertwist Nematic (STN) color LCD
which displays 640x480 pixels and 256 colors, and an electromagnetic derivative
tablet.
The T200/T200CS internal display controller supports Video Graphics Array (VGA)
on the internal/external display and Super VGA (SVGA) on the external display.
Batteries
The T200/T200CS has three different batteries: a main battery, a backup battery, and
a Real Time Clock (RTC) battery.
