Happy Quarter-Century Birthday to the HP-48SX

[Sanjeev Visvanatha]

I was in Grade 11 when the 48sx was introduced. It caught my attention, and I poured over the brochure at home. I purchased one in January 1991 and used it the remainder of Grade 12 and through Engineering Degrees and into professional life. Unfortunately the Enter Key broke one day at work, but I have a replacement I use.

Since it was my first HP, I know it inside and out. The large display, expansion ports and easy PC communications made it stand out at that time. It's slow by comparison to the GX, but I wouldn't give it up for any other stretch 48 or beyond. This calculator sparked my interest in HP calculators, so I am very fond of it. Happy Birthday!
