Casio FX-602P Series
The FX-601P and FX-602P were programmable calculators, manufactured by Casio from 1981. It was the successor model to the Casio FX-502P series and was itself succeeded in 1990 by the Casio FX-603P. Display The FX-601P series featured a single line dot matrix display with 11 characters as main display. An additional 3 digits 7-segment display used to display exponents as well as program steps when entering or debugging programs. There were 11 status indicators. Programming The programming model employed ''key stroke'' programming by which each key pressed was recorded and later played back. On record, multiple key presses were merged into a single programming step. Only a few operations needed two bytes. Synthetic programming was possible but not very common The FX-601P could store 128 fully merged steps and data could be stored in 11 memory register. The memory of the FX-602P could be partitioned between from 32 to 512 fully merged steps and data could be stored in 22 to 88 m ...

Programmable Calculator
Programmable calculators are calculators that can automatically carry out a sequence of operations under control of a stored computer programming, program. Most are Turing complete, and, as such, are theoretically general-purpose computers. However, their user interfaces and programming environments are specifically tailored to make performing small-scale numerical computations convenient, rather than general-purpose use. The first programmable calculators such as the IBM CPC used punched cards or other media for program storage. Hand-held electronic calculators store programs on magnetic strips, removable read-only memory cartridges, flash memory, or in battery-backed read/write memory. Since the early 1990s, most of these flexible handheld units belong to the class of graphing calculators. Before the mass-manufacture of inexpensive dot-matrix LCDs, however, programmable calculators usually featured a one-line numeric or alphanumeric display. The Big Four manufacturers of pro ...

Pocket Computer
A pocket computer was a 1980s-era user programmable calculator-sized computer that had fewer screen lines, Some had only one line and often fewer characters per line, than the Pocket-sized computers introduced beginning in 1989. Manufacturers included Casio, Hewlett-Packard, Sharp, Tandy/Radio Shack (selling Casio and Sharp models under their own TRS line) and many more. The last Sharp pocket computer, the PC-G850V (2001) is programmable in C, BASIC, and Assembler. An important feature of pocket computers was that all programming languages were available for the device itself, not downloaded from a cross-compiler on a larger computer. The programming language was usually BASIC.

Kansas City Standard
The Kansas City standard (KCS), or ''Byte'' standard, is a data storage protocol for standard cassette tapes at . It originated in a symposium sponsored by Byte (magazine), ''Byte'' magazine in November 1975 in Kansas City, Missouri to develop a standard for the storage of digital microcomputer data on inexpensive consumer quality cassettes. The first systems based on the standard appeared in 1976. One variation on the basic standard is CUTS, which is identical at 300 bit/s, but with an optional 1200 bit/s mode. CUTS is the default encoding used by several later machine families, including those from Acorn Computers, Acorn and the MSX. MSX added a higher 2400 bit/s mode that is otherwise similar. The 1200 bit/s mode of CUTS was used as the standard for cross-platform BASICODE distribution. KCS originated from the earliest days of the microcomputer revolution, among other prolific protocols.

TRS Connector
A phone connector, also known as phone jack, audio jack, headphone jack or jack plug, is a family of electrical connectors typically used for analog audio signals. A plug, the male connector, is inserted into the jack, the female connector. The phone connector was invented for use in telephone switchboards in the 19th century and is still widely used. The phone connector is cylindrical in shape, with a grooved tip to retain it. In its original audio configuration, it typically has two, three, four or, occasionally, five contacts. Three-contact versions are known as ''TRS connectors'', where ''T'' stands for "tip", ''R'' stands for "ring" and ''S'' stands for "sleeve". Ring contacts are typically the same diameter as the sleeve, the long shank. Similarly, two-, four- and five-contact versions are called ''TS'', ''TRRS'' and ''TRRRS connectors'' respectively. The outside diameter of the "sleeve" conductor is . The "mini" connector has a diameter of and the "sub-mini" co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casio FX-702P
The FX-702P is a Pocket Computer, manufactured by Casio from 1981 to 1984. Display The FX-702P features a single line dot matrix liquid crystal display with 20 characters. A 10-digit mantissa is displayed (including minus sign) however internal calculations use a 12-digit mantissa. Programming The programming model employed is a special BASIC dialect. Ten programming areas are supported, P0 through P9. BASIC lines can be numbered from 1 through to 9999. Subroutines are supported, but passing parameters to subroutines is not supported. The subroutine call stack can be up to 10 deep. Both GOTO lines and subroutines can be addressed indirectly via line number calculation. FOR/NEXT structures can be nested up to eight times. A single one and/or two dimensional array is supported however array memory space must be reserved (subtracted) from the 1,680 character program space via the DEFM command. Array memory can be aliased to fixed variable names, for example A(11) referen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Addressing Mode
Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. The various addressing modes that are defined in a given instruction set architecture define how the machine language instructions in that architecture identify the operand(s) of each instruction. An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants contained within a machine instruction or elsewhere. In computer programming, addressing modes are primarily of interest to those who write in assembly languages and to compiler writers. For a related concept see orthogonal instruction set which deals with the ability of any instruction to use any addressing mode. Caveats Note that there is no generally accepted way of naming the various addressing modes. In particular, different authors and computer manufacturers may give different names to the same addressing mode, or the same na ...

Synthetic Programming
Synthetic programming is an advanced technique for programming the HP-41C and Elektronika B3-34 calculators, involving creating instructions (or combinations of instructions and operands) that cannot be obtained using the standard capabilities of the calculator. Some HP-41C instructions are coded in memory using multiple byte The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit ...s. Some of these sequence of bytes correspond to instructions the calculator is able to execute, but these cannot be entered in the program memory using conventional program entry methods (''i.e.'' using the calculator as described in the user's manual.) Synthetic programming uses a bug in the calculator firmware to enter those byte sequences as a sequence of other instructions, then partially skipping halfway ...

Thermal Printer
Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by passing paper with a thermochromic coating, commonly known as thermal paper, over a print head consisting of tiny electrically heated elements. The coating turns black in the areas where it is heated, producing an image. Most thermal printers are monochrome (black and white) although some two-color designs exist. Thermal transfer printing is a different method, using plain paper with a heat-sensitive ribbon instead of heat-sensitive paper, but using similar print heads. Design A thermal printer typically contains at least these components: * Thermal head: Produces heat to create an image on the paper * Platen: A rubber roller which moves the paper * Spring: Applies pressure to hold the paper and printhead together Thermal paper is impregnated with a solid-state mixture of a dye and a suitable matrix, for example, a fluoran leuco dye and an octadecylphosphonic ...
