In May 1990, NEC marketed two new models: the PC-9801T model F5 (the first machine in Japan equipped with an 8-color TFT liquid crystal display) and the PC-9801T model S5 (equipped with a color STN liquid crystal display).
Features
- The PC-9801T model F5 was the first machine in Japan equipped with an 8-color TFT liquid crystal display (resolution 640x480 dots). The result was a vivid color display, with speed on a par with CRTs. The PC-9801T model S5 was a machine equipped with an 8-color STN liquid crystal display, and could display colors for a comparatively low price.
- These machines had two built-in slots to provide expandability rivaling desktop machines, and could be used in LANs or other networks, or connected with a variety of peripheral devices, by using expansion boards for the PC-9800 Series.
- To enable high-speed processing, they both used, as their CPUs, a 32-bit microprocessor with a clock frequency of 20megahertz--the 386SX.
