This is the Husky Hunter 16, which is an evolution of the original Husky Hunter. Developed by Husky Computers from Coventry in the 1980s for military and outdoor scientific and engineering uses. It has a ruggedized diecast aluminium alloy case which was claimed to be waterproof against accidental immersion, and if you dropped it from a height onto a concrete floor it wouldn't damage it. The Hunter 16 runs MS-DOS. This is an increasingly rare unit, especially in working condition. UK Shipping only. Please ask any questions before buying.
