Bill Hewlett told them to build one anyway. The HP-35 was the result - the world's first pocket scientific calculator, and the device that made the slide rule obsolete overnight.\u003c\/p\u003e\n\u003cp\u003eIt cost $395. Scientists and engineers bought it anyway. NASA used it. Pilots used it. It did in your pocket what had previously required a desktop machine the size of a typewriter. HP sold 300,000 in three years when they'd projected 10,000.\u003c\/p\u003e\n\u003cp\u003eThis Gizmo art print captures the HP-35 in precise technical illustration - the distinctive tall profile, the red LED display, the carefully organised rows of functions that turned a pocket-sized device into a serious scientific instrument.\u003c\/p\u003e","brand":"Axisophy","offers":[{"title":"Large (50 × 70 cm | 20 × 28 in)","offer_id":45864085225633,"sku":"AXS-GIZ-HP35-P-500x700-AM-COL","price":50.0,"currency_code":"GBP","in_stock":true},{"title":"XLarge (70 × 100 cm | 28 × 40 in)","offer_id":45864085258401,"sku":"AXS-GIZ-HP35-P-1000x700-AM-COL","price":80.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0483\/1546\/5889\/files\/Axisophy-HewlettPackard-HP35-mockup-1.jpg?v=1773752439","url":"https:\/\/axisophy.com\/products\/hewlett-packard-hp-35-calculator-gizmo","provider":"Axisophy","version":"1.0","type":"link"}
