The Advantech PCA-6178VE is an industrial-grade single board computer built on Socket 370 architecture, supporting Intel Pentium III and Celeron processors up to 700+ MHz and 1.0–1.1 GHz respectively. It combines the Intel 82440BX PCI chipset with a 66/100 MHz Front Side Bus to deliver deterministic performance in embedded control and automation environments. The board integrates on-board VGA/AGP graphics via ATI Rage Pro Turbo or ATI RAGE XL with 4–8 MB video memory, 10/100Base-T Ethernet with Wake-On-LAN, dual Enhanced IDE interfaces supporting ATA 33 at up to 33 MB/sec throughput, and an Ultra II SCSI controller for flexible storage connectivity.
