486 SBC with VGA/LCD, Ethernet and SSD

PCM-4862 Introduction

The PCM-4862 is an enhanced, all-in-one single board 486 computer with an on-board Ethernet interface, local-bus VGA controller and solid state disk. The PCM-4862 offers all the functions of an AT-compatible industrial computer on a single board, but it fits in the space of a 5.25" floppy drive (only 5.75" x 8"). For maximum performance, the PCM-4862 also supports 2nd level cache sized from 128 KB to 512 KB (32 KB x 8, 64 KB x 8, or 128 KB x 8).

An on-board solid state disk (SSD) emulates a floppy drive using EPROM or Flash memory devices. You access the SSD using standard DOS commands or BIOS I/O. The system can even boot from the SSD. Disk capacity it up to 1.44 MB, depending on the size of the memory chips, or up to 144 MB if using a DOC?/font> 2000 Flash disk module. If you use Flash memory, you can read and write to the disk just like a floppy. If you use EPROM, the disk is read-only and you must program the chips with an EPROM programmer.

The PCM-4862 also complies with the "Green Function" standards and supports three types of power saving features: Doze mode, Standby mode and Suspend mode.

All display and Ethernet configuration is done through software. A single Flash chip holds the system BIOS, VGA BIOS and the network boot ROM.

If you need any additional functions, you can add up to six industry-standard functions, we have developed a PC/104 to ISA adapter so you can use you standard ISA cards.
