Vintage HP-12 Calculator - Never Used - In Original Box with Book - RARE

Own the calculator that built Wall Street: The original HP-12C. This nearly mint, vintage offering includes the original book (first printing circa 1987), calculator, case, and the original box and packaging. I've replaced the batteries and ensured all works, but otherwise this is the same calculator everyone used back when the Dow was at about 1950 and 30-year mortgages were running over 10%. Seriously, this remains a workhorse calculator for anyone in the financial services industry. Oh, and I have it from a good source that THIS particular calculator is the one that has all the right answers inside it. 2401-66N
