The SBC-590 is an all-in-one single board Pentium computer with an
on-board SVGA controller, with PCI-bus and ISA-bus support. It
packs all the functions of an industrial computer with display capabili-
ties on a single full-size card. The SBC-590 is fully PC/AT compati-
ble, so your software will run without modifications.
The on-board PCI-bus SVGA controller uses the ALG 2032 chipset
with 1 MB shared memory. This chipset, used with the local PCI-bus,
enables 32-bit graphic throughput and has a built-in Standard
Feature Connector. These features make the SBC-590 particularly
suited for graphics intensive applications.
Another feature of the SBC-590 is the inclusion of a high speed local
bus IDE controller. This controller supports (through ATA PIO)
mode 3 and mode 4 hard disks, which enables data transfer rates in
excess of 11 MB/sec. Up to four IDE devices can be connected,
including large hard disks, CD-ROM drives, tape backup drives or
other IDE devices. 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 accomplish the IDE boost in performace improvements.
On-board features also include two high-speed RS-232 serial ports
with 16C550 UARTs, one bidirectional SPP/EPP/ECP parallel port
and a floppy drive controller. In addition to the Pentium's 16 KB of
on-chip cache memory, the SBC-590 comes with an extra 256 KB or
512 KB of second level memory on-board.
If program execution is halted by a program bug or EMI, the board's
16-stage watchdog timer can automatically reset the CPU or generate
an interrupt, provided the watchdog timer has been programmed in
advance. This ensures reliability in unmanned or stand-alone systems.
The SBC-590 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 eco-
nomical combination of SIMMs.
