The AT91SAM7L128 is a member of a series of high-performance, ultra-low power ARM7TDMI-based Processor. The ARM7TDMI RISC processor based on ARMv4T Von Neumann Architecture, runs at up to 36 MHz, providing 0.9 MIPS/MHz. Two instruction sets: ARM high-performance 32-bit instruction set and Thumb high code density 16-bit instruction set. Three-stage pipeline architecture: 1. Instruction Fetch (F), 2. Instruction Decode (D) and 3. Execute (E). Memories: 128 Kbytes of Flash Memory (AT91SAM7L128) - Single plane, One bank of 512 pages of 256 bytes, 10,000 write cycles, 10-year data retention capability, Protection Mode to secure contents of the Flash.

HP50g Full Specifications Calculating Environments \* RPL-style RPN (Reverse Polish Notation) \* EOS-style algebraic \* Equation Writer (textbook-style input) \* Stack display shows 7 lines by default, but it can be increased to 8 or 9 by shrinking or removing the header \* Header shows current directory path and important settings, and optionally can display a digital or analog clock Expandability \* SD card slot, with support for industry-standard cards up to 2 GB formatted as FAT16 (full support) or FAT32 (partial support)

If the settings are too confusing, it is always possible to do a full reset of the calculator by pushing an unfolded paper clip into the RESET hole at the back of the calculator. The calculator is reset but the contents of memory are retained, only the stack is cleared. Alternatively, you could perform a reset - Press and hold the top left and right keys then the [ON] button, the 50g beeps and asks whether the user wants to try to recover the contents of memory.

HP 20b Depreciation Straight-Line Method A metalworking machine, purchased for $10,000.00, is to be depreciated over five years. Its salvage value is estimated at $500.00. Using the straight-line method, find the depreciation and remaining depreciable value for each of the first two years of the machine’s life. Press [Shift] [Depn] keys to open the Depreciation menu starting with the “SLine” straight line method. Press [Down Arrow] key the prompt displays “Life” or the current value of the useful life.

The simplest and most commonly used, straight line depreciation is calculated by taking the purchase or acquisition price of an asset subtracted by the salvage value divided by the total productive years the asset can be reasonably expected to benefit the company called “useful life” in accounting jargon. Annual Depreciation Expense = purchase price of asset - approximate salvage value ———————- (divided by) ———————- estimated useful life of asset Example: You buy a new computer for your business costing approximately $5,000.

The Data menu allows you to enter up to 50 pairs of statistics data. The Memory is shared between the data and cashflow areas, the 20b has 50 slots for pairs of statistical or cashflow data in total. If you try to enter the STATS menu before you have entered any data, the 20b will enter the Data menu for you. Numbers are entered, pressing [INPUT] in between them. Once your data is input, enter the [Shift] [Stats] menu.

Selected models on the HP Calculators lineup have special keyboard contacts that give positive ’tactile feedback’ so you know the button has been depressed. The rotating design ensures contact even when pressed off-center, which prevents missed input strokes. HP calculators HP 30b, HP 39g+, HP 39gs, HP 40gs, HP 48gII, HP 49g+, HP 50g, HP10bII, HP 12c, HP 12c Platinum, HP 12c, HP 17bII+, HP 33s and HP 35s adopted the HP’s accurate rotate-and-click keyboard technology.

CAS Equation Writer The HP 40g Equation Writer enables you to type expressions that you want to simplify, factor, differentiate, integrate, and so on, and then work them through as if on paper. The {CAS} key on the home menu bar takes you into the Equation Writer, and the [HOME] key takes you back out to the HP 40gs Home View Screen. The Equation Writer is a very efficient editor for writing, simplifying and transforming mathematical expressions.
