Notes:	The HP 48 series of calculators preserves the wonderful look of HP’s calculator heritage. Different buttons but the same sturdy feel. Despite the many functions I think the keyboard looks really balanced. Accented function keys at the top. A beautiful machine to look at. The HP 48SX is part of a series of HP 48 calculators. Wikipedia lists (link valid 2024-01-13) the following family members: HP 48G HP 48S HP 48SX (this one) HP 48GX HP 48G+ ThiThese calculators have everything one might need. One might wonder how such a calculator could ever be succeeded. In fact this calculator has so many functions that it will be hard to produce a TL;DR, I won’t even try. A Quick Guide manual of the HP 48G (a sibling) and the HP48GX’s User Guide can be downloaded here from hp.com. The HP 48SX has 32 kB of on-board RAM which can be extended to 128 kB (see Peripherals). Much better battery life than the HP 49G. For more information on this beauty please refer to the better sources, like The Museum of HP Calculators (link valid 2024-01-13).
