Up for bid on eBay is an original HP-70 calculator owner's manual (printed in July 1974).
According to VintageChip.com, the HP-70 calculator was introduced on August 1, 1974 as part of the Classic Series. It was the 2nd business calculator and 5th handheld electronic calculator. It was code named "Scrooge". The HP-70 was a very unpopular product and was discontinued after just one year, which is why it is one of the rarest calculators and hard to find in any condition.
The seller says, "I do not remember where I got this from. I have been a hp collector for over 20 years and the HP70 was the one calc that eluded me all those years. I think I got this in a box of manuals that I bought and I kep it hoping that I would one day match it up with the calc. I am in the process of liquidating my collection so there is no need to hold onto it now. If you are one of the lucky collectors who managed to collect the HP70. This would be a great addition to your collection. Even if you already have a manual...you may want to upgrade the manual to one that is almost pristine. If you own a 70 without the manual..this will complete the set."
