The WinSystems PCM-586-2801B is a PC/104 single board computer built around the AMD 5×86 processor running at 133 MHz with integrated 80-bit floating-point unit and 16 KB onboard cache. This PC-AT compatible board delivers embedded computing in a compact form factor, supporting DOS, Windows CE, and Windows 3.1/95/98/NT operating systems. Equipped with up to 32 MB of EDO DRAM, dual serial ports, IDE and floppy disk controllers, parallel printer port, and keyboard/mouse interfaces, the PCM-586-2801B provides a complete I/O subsystem on a single module.
Technical Specifications
