Happy Quarter-Century Birthday to the HP-48SX

[Chris Randle (UK)]

The 48SX was my first HP calculator too, and the precursor of much mental illness since ;-)

I've fished out the receipt from February 1991. I paid £310 for it, which was probably around US$500 back then.

   

I still have it, and it still works perfectly.

I coveted a 48GX, but could never justify the cost for an upgrade to what I already had.
