AAEON SBC-490 CPU Board. Full-size 486 PCI/ISA-bus CPU Card with SVGA interface, accepts 486 compatible processors, fully PC/AT compatible Simple Type: CPU Board

The SBC-490 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-490 is fully PC/AT compatible, so your software will run without modifications. The SBC-490 is excellent for display-intensive applications. The on-board 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. In addition, the SBC-490 features a high speed PCI-bus IDE controller, which connects up to four IDE devices, including large hard disks, CD-ROM drives, tape backup drives or other IDE devices. It supports(through ATA PIO) mode 3 and mode 4 hard disks, enabling transfer rates of over 11 MB/sec. The built-in enhanced IDE controller provides a 4-layer 32-bit posted write-buffer and a 4-layer 32-bit read-prefetch-buffer to boost IDE performance. On-board features also include two high-speed RS-232 serial ports with 16C550 UARTs, one bidirectional SPP/EPP/ECP parallel port and one floppy drive controller. In addition to the 486's 8 KB of on-chip cache memory, the SBC-490 comes with an extra 128 KB or 512KB of second level memory on-board. If program execution is halted by a program bug or EMI, the board's 15-stage watchdog timer can automatically reset the CPU or generate an interrupt. This ensures reliability in unmanned or stand-alone systems. The SBC-490 supports 5V EDO DRAM. It also provides four 72-pin SIMM (Single In-line Memory Module) sockets for its on-board system DRAM. These sockets give you the flexibility to configure your system from 1 MB to 128 MB of DRAM using the most economical combination of SIMMs. For optimal power management, the SBC-490 also supports the "Green" function.
