HP · Voyager · Announced September 2011
Owners kept asking HP to bring back the 15C, and on September 1, 2011 HP did. A prototype marked 15c+ had shown up at a collectors' conference the year before. The Limited Edition looks like the 1982 calculator and runs the same firmware, but inside an ARM processor emulates the old chip at least 150 times faster, on two coin cells. Memory is unchanged at 67 registers. HP released it alongside the 12C 30th Anniversary Edition, and it has since been discontinued. It's a great way to use a 15C every day, with two catches documented on the HP museum's bug list: PSE misbehaves in programs, and the original self-test can scramble memory.

Bench check
Should come with it
Check the listing photos against this list, and ask the seller about anything you can’t see. A missing piece should come off the price.
The release firmware's PSE bug and the broken original self-test are documented. Otherwise check the coin cells and every key.
New to old calculators? The condition checklist covers battery corrosion, displays, keys and card readers, and RPN in one hour gets you typing on an HP.
Buying guide
We'd buy the LE with its box, manual, CD and papers at $267 delivered, since it's the most complete kit here and asks less than most of the others. Only 8 are listed, so the $280-600 band isn't a real market read. Five US units ask $200-312 delivered, one US unit asks $566, and two open-box units from Japan ask $638 and $831. Check the photos show Limited Edition under the HP logo, and ask for a photo with the battery door off, where two CR2032 cells belong. The original 15C self-test can scramble an LE's memory, so ask the seller to hold g and ENTER while pressing ON for the new test menu instead.
$200.00delivered
The lowest ask at $200 delivered, titled mint with a case, and the photo shows the Limited Edition marking. It isn't titled tested, so ask for a photo of it switched on and one with the battery door off.

The photo shows it switched on, and at $290 delivered it sits at the bottom of the band. It isn't titled tested and no box shows, so ask for the g, ENTER and ON test menu before you pay.
