Re: Compare 48G/GX and 48S/SX Message #6 Posted by Christoph Giesselink on 5 Mar 2005, 9:49 a.m., in response to message #1 by Dan Kalish
Because you are already working with 48G I would suggest that you're looking for a 2nd one in the 48G Series (G/G+/GX).
The 48S/SX has the same layout and most of base build in functions are equal. Of course there must be a difference because the 48S series has 256KB ROM where the G series has 512KB. There's also a speed difference the G series is ~ 50% faster than the S series.
One of the most important reasons IMHO is the place of the functions in the soft menus. Most of the functions are equal but reside on a different place in the menue structure. Especially when you use the "Pop-Menus" you will have problems, because the S series haven't them. I'm telling this because I'm a user of a 48SX and here I have problems using one of my 48GX.
When you're are using programs from various authors written in SysRPL or assembler you will have compatibility problems. I recognized that in the last 6-8 years more and more programs are only for the G series and the developers don't care about the S series any more. But this is a result that the HP48G is newer, sold for ~10 years (aka ~4 years SX) and in general much cheaper (I payed 1995 for a new HP48GX half of the price as for my 48SX in 1991). SysRPL and assembly program must specially designed to run on all HP48.
Finally some words to eBay (Germany) prices. 48S and 48SX have nearly the same prices, maybe that the S is about $ 5-10 cheaper. A G series costs about 60% more where especially the 48G are overpriced. For a little more bucks you can get a 48GX with 128KB RAM instead of 32KB. 48G+ are quite rare and have nearly the same price than a 48GX. Because of this I have ~ 5 GX but no G or G+. Like on many other products there are seasons with high prices (especially before X-mas) and times with lower ones. I just bought a 32S (after looking for one over two years) in used and quite good condition at eBay for 45 EUR (~ $60). Two weeks ago a saw a HP48GX with manual sold for 65 EUR (~ $85), that definitely much below the $100 border.
