    Hp-48sx

    Among the Engineers that I know, about 15-20% of us are fiercely loyal to HP's RPN logic and the "functional stack" of HP's handheld programables. I have two 48SX's. One has lost its internal memory and I'd like to get it repaired. I think that it has been through the airport X-ray machine too many times. The problem is that these calcs were made in the 80's and HP won't even admit that they ever made them. Is there anyone here similiarly obsessed/infected that knows a solution? I'm starting to feel like John Titor looking for his IBM 5100! DRB

    For those not in the know about this particular model of calculator.

    Ebay has a few for sale:

    And if you are determined to repair it:

    Repair Manual

    Contains documentation and 45 photographs explaining how to open the HP 48 series for repair, including tips on repairing screen and keyboard problems.

    Photos (and a very brief explanation) of a 48 SX upgrade with a 128 K SRAM.

    I think if you are serious about this the following site will definitely aid you in your repair:

    BB, WOW! Thanks for the links! I did what I thought was a good search about two years ago (about when HP and Compaq got together), and couldnt find much. It's hard to believe there is that much interest in a calculator that was last made 13 years ago. DRB
