General Dynamics GoBook XR-1
General Dynamics are better known for fighter jets, but they also made rugged laptops – admittedly by purchasing Itronix. The GoBook XR-1 was the first laptop to wear the General Dynamics badge, and it was a very well put together machine. Designed to compete with the Panasonic CF29, the GoBook is a die-cast magnesium laptop weighing 6.8lb. Notable features included an outdoor-viewable (sunlight readable) display called DynaView. According to GD “DynaVue® exceeds the minimum contrast ratio as required for bright sunlight per dod-std-3009” so it must be good.
“Structural components” are die-cast magnesium. The case features an integrated handle which makes lugging the GoBook around a little easier. It’s quite a dense computer – 12.1″ display, and measuring:
- Length: 9.65” (24.5 cm)
- Width: 11.8” (30.0 cm)
- Depth: 1.98” (5.0 cm)
it still weighs 6.8 lb (3.1Kg). Along with Getac computers the Itronix featured a hard disk drive heater to ensure the computer would boot when cold. That allowed a temperature spec of -10°F to 140°F (-23°C to 60°C).
