Snip:The HP-15C calculator was produced by Hewlett-Packard from 1982 until it was discontinued in 1989. It had an original MSRP of $134.99. The 15C was part of HP’s Voyager line of calculators that began in 1981. The Voyager line, including the 15C, are all programmable calculators and use Reverse Polish Notation. The line included the 10C, 11C, 12C, 15C and 16C. They all look similar but each one has different capabilities and were marketed to different groups of users.The HP-15C was the advanced scientific calculator in the Voyager lineup and took the place of the earlier HP-34C. In addition to the 34C’s capabilities the 15C can manage matrix operations, complex numbers, numerical integration and root solving. It has a 10 digit, 7 segment LCD display.Specifications:Entry mode: RPNDisplay type: LCD seven-segment displayDisplay size: 10 digitsCPU Processor: HP Nut core (1LF5 / 1LM2 / 1LQ9[1]) / ARM7TDMI core (Atmel AT91SAM7L128) (15C LE)Programming language(s): Keystroke programmable (fully merged)Memory register: 2…66 registers (R0…R9, R.0/R10…R.9/R20, R21…R65) plus RI, X, Y, Z, T, LAST XProgram steps: 0…448 linesScientific programmableComplex number functionsMatrix arithmeticSolve functionIntegrate functionStatistical functionsLinear regressionStorage arithmeticRPN 4 level stack with parallel 4 level stack for complex numbers448 bytes continuous memoryDefault 322 bytes program memoryDefault 21 addressable memory registersSingle line 10 digit, 7 segment LCD displayPower consumption: 0.25 mWWeight: 113 gDimensions: 128 × 79 × 15 mmThe HP-15C was a very popular calculator. When it was discontinued in 1989 prices shot up on the after market. HP eventually capitalized on this demand and released the HP-15C Limited Edition calculator in 2011. It has the Limited Edition script underneath the logo and you can see that the logo has different coloring as well. Only 10,000 units were made.Inside, the Limited Edition HP-15C utilizes a newer CPU that emulates the Saturn CPU and runs the original ROM code. Of course, that means that some of the functions run far faster than the original.One of the reasons that the original 15C is still so popular is because it does not have alphabetic characters so it can be used in many testing situations that most newer calculators cannot. Of course, it’s small size, portability and horizontal shape are advantageous as well.The HP-15C is one of the best calculators that Hewlett-Packard ever made. The algorithms used are excellent, the key layout is jam packed but efficient, and it’s size and features are great for almost any situation. Overall it is a fantastic calculator.

Hewlett Packard HP-15C Scientific Calculator Single Owner Works Great Condition. This is the calculator that helped me get into MIT (Class of 89!). It uses Reverse Polish Notation (RPN) which is easy to learn and fun to use, e.g. instead of typing 3 + 5 = you type 3 5 + which returns 8. It also stores and recalls functions (macros) to simplify repetitive problem solving. It works great, just like it always has; I do not include batteries because I prefer to avoid shipping batteries through eBay sales. There are a few minor scratches on the top left front face (see pictures) which do not in any way impact the use of this device. Includes soft case which is also in great condition. Here is a link to a number of sites providing the user manual for this calculator:https://duckduckgo.com/?q=HP+15C+calculator+manual&atb=v314-1&ia=web Thanks for looking! Bid high and have fun!

Awesomest calculator ever made! Hewlett-Packard HP 15C scientific calculator dates to the mid-1980s; got me through my first few years of engineering school. This one is a beat. Missing its 15C badge, has some dents to case and feet on back are worn or missing. Calculator works great. Fully functional but likely needs some new batteries. Reverse Polish Notation is a must for crunching equations. Case is a bit distressed but still functions. See photos for more details.
