HP’s First Handheld Computer: HP-75C

HP-75C Long before you had netbooks and proper PDAs, HP introduced its first handheld computer in 1982. It was tiny – we’re talking 10- by 5- by 1-inches. To put that in perspective, that’s about the size of a magazine. (You remember what those look like, right?) It packed a whopping 48K ROM and 16K RAM (and three ROM expansion ports), the HP-75C ran BASIC and VisiCalc. Back then, it was a number of things – including one of the earliest organizers. The appointment alarm mode would let you set one of 10 alarms styles (like the ever-so-popular “A short chirp” or the more hardcore “A series of eight siren sounds”) and attach a text file to the alarm.
