Overview
The Half-EBX PC is the ultimate cost-effective solution for limited space applications. These small all-in-one computers are the same size as a 3½” hard disk drive and perform all the functions of an industrial computer and more! The PCM-4823 and PCM-4823L Half-EBX PCs are ultra-compact single board computers that integrate a 32-bit SVGA and LCD interfaces (PCM-4823 only) for a complete processing system.
On-board features include an Intel® DX4-100 processor, floppy disk controller, parallel port, an EDO DRAM SIMM socket, enhanced IDE, keyboard/mouse connector, and two standard serial ports. As energy efficient as it is space efficient, the PCM-4823/23L also supports power saving modes for I/O peripheral devices.
 The PCM-4823 and PCM-4823L Half-EBX PCs are built especially for limited space embedded applications. Based on PC/AT architecture, they are compatible with most off-the-shelf software. In addition, because of the availability of inexpensive PC platforms, using the PCM-4823 or PCM-4823L can significantly reduce development time and cost. Moreover, mechanical configuration and system expansions are simple with industry standard PC/104 carrier modules.
