48S/SX - scientific expandable graphics calculators;
48SX launched first with PCM-CIA slots (up to 1MBYTES RAM or 4MBYTES with switching banks);
48S launched a bit later, without PCM-CIA slots; both with 32KBRAM, RS232, Kermit and IR I/O capabilitites; interface based in RPL, sort of RPN (like the HP41) with multilevel, numbered stack; programming language is like FORTH+LISP recursive; algebraic capabilities with many manipulating resources, like derivatives; may be seen as a "fusion" of the best of two words: HP41 and HP28
48G/GX/G+ - expanded graphics version of the S series (3D plotting and more), all resources above and a few differneces:
G - 32KBytes RAM
G+ - 128KBytes RAM
GX - 128KBytes RAM and PCM-CIA slots
There are many other features, these ones I know by heart.
HP49G - I am not aware of these two models, except for the fact the first series had a sort of HW bug with the I/O port; these calculators have FLASH ROM (1MBytes)so you can update the O.S.; also they have user FLASH-ROM (1 MBytes) and user RAM (2 banks with 256KBytes)
If you need more, post again. There are pages (I do not know the links) in the Internet with more info; surely someone will post them here.
Lost contact; read the PDF I sent you?
