MilPAC is a sealed and ruggedized, dust and dirt proof, indoor/outdoor portable computer. For field ruggedness, the computer’s case is formed from corrosion-protected aluminum, designed to shield the internal components from up to 40Gs of shock. For environmental protection, it is IP 54 rated for weatherproof storage and transit. An upgrade to the MilPAC Plus provides an IP 65 rating for water resistant operation. The fold-up keyboard protects the 14.1 hi-bright XGA TFT display. This 150-nit active matrix screen provides read-ability even in bright ambient light conditions. Add-in expansion is via three open PCI slots or optional PCMCIA slots. Worldwide functionality is assured by 110/220 VAC augmented by an external 12 VDC adapter.
