Vintage HP 20S Scientific Calculator -- 1987 -- This calculator is in mint condition. I cannot find even a surface scratch on display or any side of plastic (Front, Back, Sides) Keys are clean (even around keys) No sticking keys. Battery compartment is also pristine. Of course it works as it should. Case is also pristine, with no blemishes, cuts or scrapes. I would think it would be very, very difficult to find one of these in any better condit...ion. Please take a look at pics as they tell the story of condition. PayPal only. Thanks for looking!!!!!
