Model: 48S, differences from 48SX General: Name: Scientific Code-Name: Shorty Firsts: none Introduction: Date: 1991-04-02 Price: $250 Discontinuation: Date: 1993-06-01 Price: ? Production-Run: ? Physical: Expansion-Ports: none Weight: <264g Notes:: This is a 48SX without the expansion slots. Joseph K. Horn has come up with this list of differences: (1) The obvious difference: The 48SX is "eXpandable" (you can plug one or two cards into it, RAM and/or ROM, to expand its operating system and/or its 32K native RAM); the 48S is not. (Corollary: the 48S cannot run much of the best software written for the 48). All other differences are minor; here they are anyhow: (2) The 48S beeps twice as loudly as the 48SX. (A side effect, in more ways than one). (3) Every 48S (to date) is an "E" version 48; the 48SX can be found in five different versions from "A" to "E". (The 48S has *exactly* the same operating system as the 48SX rev E, bit-for-bit). (4) The port cover on the 48SX extends almost down to the rubber feet, and can be removed. The "port cover" on the 48S only covers the very top of the calculator, and cannot be removed. Their back shells differ accordingly. (5) There is a port number diagram molded into the back shell of the 48SX, between the upper two feet. The 48S has no such diagram. (6) The "[(hp)] HEWLETT PACKARD" logo on the front of the 48SX is a separate plastic applique, rising above the surface through a hole in the metal overlay (thus allowing card-customized 48SX's to sport their own logo). The 48S has its HP logo merely printed on the metal overlay in the same color as the "48" immediately below (because the 48S cannot be customized by plug-in cards). (7) The 48SX has "48SX SCIENTIFIC EXPANDABLE" printed above the display; 48S has "48S SCIENTIFIC". (Besides #6 and #7, their fronts look identical). (8) The 48S costs much less than the 48SX. (9) A TI rep at the Consumer Electronics Show stated to me that the TI 85 is trying to compete with the 48S, not the 48SX (which has no competition from anybody).
