Taiwan-based board vendor Acrosser has introduced a single-board computer (SBC) optimized for arcade gaming. The AR-B5290 follows the mini-ITX standard hole locations, providing mounting flexibility, but adds a "JAMMA" edge-card interface for compatibility with arcade game cabinets, according to the company. The AR-B5290 can be configured with Pentium M or Celeron M processors that have a 400 or 533 MHz front side bus, Acrosser said.
Two DIMM sockets support up to 2 GD of DDR2 SDRAM. Display outputs include analog VGA and dual 18-bit LVDS. The board's arcade game-oriented expansion interface is based on a standard created by the (JAMMA).
In the mid 80s, JAMMA introduced a wiring standard for arcade cabinets that allows a cabinet to be upgraded to a different game simply by swapping out the game SBC. The JAMMA interface is implemented via a 56-pin edge card connector that provides signals for two 8-direction joysticks, two player start buttons, six control buttons (three per player), and monaural sound.
