I recently acquired a mint HP-65. This calculator is in perfect shape cosmetically and appears to be just like new. The trim is perfect, the feet are perfect, all the digits light up, and it calculates just fine. No scratches or wear anywhere. The unit could definitely be on display at a museum, it's that good.
There is one problem: The built-in card reader runs, but does not pull cards through. Instead, a gummy substance is left on the edge of the card. It's the O-ring deterioration problem again, and the question is this:
Should this otherwise pristine HP-65 calculator be opened to fix the card reader? Doing so would require damaging the (perfect) foil reference label on the back to gain access to the screws. So, is fixing the card reader worth damaging the label? I should say I have an assortment of accessories for this calculator, including the hard plastic case, the leather case, charger, and four application pacs, all in fabulous condition.
I would like to get advice from other collectors on whether I should have the card reader fixed or not.
I look forward to hearing from everyone.
Thanks,
Todd
