The SBC-492 is an all-in-one single board 486 computer that includes an on-board SVGA controller, with PCI-bus and ISA-bus support. It packs all the functions of an industrial computer with display capabilities on a single full-size card. The SBC-492 is fully PC/AT compatible, so your software will run without modifications. The SBC-492 is excellent for display-intensive applications. The onboard PCI-bus SVGA controller uses the Trident TGUI9440GUi chipset with the local PCI-bus to enable 32-bit graphic throughput at up to 33 MHz. Also built in is a standard Feature Connector.
