Happy Quarter-Century Birthday to the HP-48SX

[Dave Britten]

The 48SX was pretty much a refinement of the RPL system, married to the 41C's approach to customization and expansion, and if that doesn't make you feel tingly inside, then you're on the wrong web site.

The 48SX is still my preferred desk calculator. The screen contrast is poorer overall than the GX, but the range of usable viewing angles is much wider. Load GXLib on it to regain some of the list processing commands the GX introduced (DOLIST and DOSUBS in particular), and you've got a pretty nice system overall.
