Happy Quarter-Century Birthday to the HP-48SX

[John R. Graham]

The 48SX was the 2nd calculator (the 41C being the first) that I purchased with my own money, bought at the Engineer's Bookstore just outside of the Georgia Tech campus sometime in (I believe) 1990. An absolutely revolutionary machine at the time. My fingers still use chords I learned on the 48SX when playing my 50g.
