Re: HP 48SX vs 28S Message #8 Posted by Masao Kinoshita on 6 Dec 2007, 2:43 p.m., in response to message #7 by Keith Beyer
Hi,
Reading your post, I now remember that the HP 48SX was a tad slow at solving those equations. The HP 48GX is a faster machine, with its Saturn processor over-clocked by design by HP. Using the equation writer "feels" much better on the GX for the same reason.
The serial interface kit for the HP 48SX/GX might be a special order item at HP. Googling for it, I found the follwing Web page (HP Graphing Calculators - Accessories):
