An iconic 44-year-old HP programming calculator is back with a few upgrades. (opens in new tab)

The original HP 16c launched in 1982 as a calculator programmers could use for coding and debugging. Production stopped in 1989, but Moravia Education has resurrected the HP 16c with a faster processor and the ability to now save and load programs. Only 10,000 are being made for $129.95 each.
