Omschrijving
Collectors item!
Van deze speciale verjaardagsversie van de 14B voor het 50 jarige bestaan van HP zijn er slechts enkele gemaakt.
Nieuwe HP-14B Anniversay Edition (50 jaar HP 1939-1989) in originele staat en verpakking.
Along with a version of the HP-32S, this version of the HP-14B was developed as part of HP's 50th anniversary celebration. Other than the two anniversary logos on the calculator and one on the case it had the same features as the regular HP-14B including:
INPUT & SWAP
While this was an algebraic calculator, the INPUT key had some of the functionality of an ENTER key. It was used to enter data in response to prompts and was also used to enter pairs of numbers for two variable statistical functions. In the latter case, the user entered the x value, pressed INPUT, entered the y value and pressed the appropriate stat function key.
The SWAP function would also be familiar to RPN users. It reversed the positions of the current and previous numbers. For example to subtract the number in the display from the number 10, the user would press - 10 SWAP =.
Applications and the COMPUTE Key
The calculator contained several business applications. Some applications such as Time Value of Money were assigned a set of keys of their own but other applications had a single dedicated key which brought up a scrollable display of variables.
The user could move to a variable using the up and down arrow keys, enter a number and press INPUT. After inputting all the data, the user could solve for the unknown variable by moving to it and pressing COMPUTE.
The calculator's applications were:
Time Value of Money.
Cash-flow calculations.
Three percentage applications {cost, price, margin}, {old, new, percent change}, and {total, part and percent total}.
Interest rate conversion (nominal, effective and differing compounding periods.)
Return on investment analysis.
Break even analysis.
Inventory turnover rate analysis.
The calculator also included statistics functions such as:
One and two variable mean and standard deviation.
Forecasting and curve fitting (with automatic or manual selection of curve-fit model.)
Weighted mean.
