Arcom APC Computer

The Arcom APC Computer is a single-board computer engineered for embedded systems in industrial control, data acquisition, and communication applications. It delivers configurable processor options—AMD SC520 at 133 MHz, AMD K6-2 at 300 MHz, or Intel Pentium 4/Celeron variants—paired with scalable memory architectures supporting up to 64 MB SDRAM or 2 GB DDR SDRAM depending on model. The platform integrates flash storage up to 16 MB, IDE hard disk support, and optional battery-backed SRAM. Connectivity spans four high-speed UARTs (RS-232, RS-422/485, TTL), 10/100 BaseTx Ethernet, and extensive expansion via PC/104 format compatibility with 10 legacy ISA slots and 4 PCI revision 2.2 slots. Operating temperature ranges from -20°C to +70°C across standard models, with Panel PC variants rated 0°C to +50°C. Power supplies scale from 100 W to 450 W depending on configuration, with input acceptance of 95–250 V AC (50–60 Hz) or 11–32 V DC. The platform runs DOS 6.22 through Windows XP Embedded and includes embedded BIOS 4.3 with onboard reprogramming capability and programmable watchdog timer functionality (32–492 seconds).
