The Casio FX-7000G is a calculator, known as being the world's first graphing calculator available to the public. It was introduced to the public and manufactured between 1985 and c. 1988. Notable features are its ability to graph functions, that it is programmable; the calculator offers 82 scientific functions and is capable of manual computation for basic arithmetic problems. The calculator can compute basic arithmetic functions with a precision up to 13 digits. Many functions integrated into the calculator include arithmetic and algebraic computations such as: square roots reciprocals exponential functions factorials logarithms trig functionsOther specialized functions implemented into the calculator include hyperbolic and statistical functions, binary/octal/hexadecimal/sexagesimal conversions and graph plotting. Like many Casio calculators, the FX-7000G includes a programming mode, in addition to its display and graphing mode, it holds 422 bytes of less than half a kilobyte. However the calculator does allow for expanded/additional memory by a method of reducing the number of steps within a program.
This is done by optimizing the number of steps a program has to fill a single unit of memory, instead of several. The user may save any program they create or are in the process of creating in one of ten programming slots, a feature used in the Casio BASIC handheld computer; the calculator uses a tokenized programming language, well suited to writing more complex programs, as memory efficiency is a priority. Tokenization is performed by using characters and symbols in place of long lines of code to minimize the amount of memory being used; the User Manual programming catalog is written in these symbols, allowing for lengthier programs to be written with less effort and less memory. One example is a program; the calculator has 26 numeric memories as standard. Additional memories can be created by reducing the number of bytes available for programs. Using this facility allows a total of 78 memories maximum; the calculator has a built in graphing feature, unique to its model. The calculator can display either built-in graphs that are programmed or display a user defined graph.
The user has the option to rewrite any of the programmed graphs. Statistical graphs can be generated: bar graphs, line graphs, normal distribution curves, regression lines; the FX-7000G incorporates an LCD Dot Matrix design via the display window. When set into character mode the calculator can display up to sixteen characters on each of its eight display lines; this sixteen character by eight line display is screened on the 96 × 64 dot matrix. The LCD is not capable of colour or grey scale display. A black casing surrounds the calculator along with a metal panel implemented on the rear. Keys are labeled and printed on orange, blue and black malleable buttons; the calculator's dimensions are 83.5 mm × 167 mm × 14 mm. It has an approximate mass of 155.5 g including batteries. The Casio Fx-7000G needs a 9.0 volt DC current lithium battery supply provided by 3 CR2032 type cells. The calculator only uses batteries; the average battery life is around 120 hours, shorter in length compared to similar models.

Casio 9860 series
The Casio fx-9860G is a series of graphing calculators manufactured by Casio Computer Co. Ltd, successor of the fx-9750G PLUS/CFX-9850 PLUS/CFX-9950 PLUS/CFX-9970 family of calculators. All of them are capable of being programmed by means of sophisticated languages and tools including assembly language, Basic variants, ports of programming languages such as C, as well as hosting add-ins which are compiled on a computer and downloaded to the calculator. Changes from fx-9750G PLUS, CFX-9850 PLUS, CFX-9950 PLUS, CFX-9970 series include: Increase program capacity to 63,000 bytes and storage memory capacity to 1.5 MB. The Casio Basic variant on these calculators is a more comprehensive version: string functions, additional control and branching statements Addition of USB 1.1 port. New modes include spreadsheet, eActivity. For models with SD suffix, support of Secure Digital memory cards. There are several versions of the fx-9860G; the AU version used to limit the amount of internal flash memory available to 800 Kb to meet Australian school regulations, although it has now been upgraded to 1.5 MB.
The SD variant comes with an SD expansion card slot, allowing read and write access up to 2 GB of memory on a SD memory card. The Slim version has a back-lit display, on-board help, is designed as a clam-shell to minimize its size; the usual fx-9860G and fx-9860G SD are marketed in France as Graph85 and Graph85 SD. The calculators can be programmed in different ways; the fx-9860G's come with a built-in BASIC-like interpreter, allowing the user to create simple and complex programs using built-in functionality. The other method is to create an add-in. Add-ins are binary programs, executing directly on the calculator's CPU. CASIO has released two official add-ins, GEOMETRY and PHYSIUM. An SDK was released by CASIO in 22/01/2007, allowing users to create their own add-ins, though no support is provided for this by CASIO; the add-ins and the SDK are available for registered users at CASIO's website. The calculator supports connecting to computer via USB cable. USB connectivity requires installation of USB driver and Program Link software from the bundled CD-ROM.
The 3-pin COM port supports transferring data between other CFX-9850/fx-7400 series calculator up to 9600 bit/s, other fx-9860G series calculator up to 115,200 bit/s. The fx-9860GII and fx-9860GII SD became available in May 2009; these calculators have backlit displays and the Geometry and ECON2 apps preinstalled. They have new mathematical functions; the French versions of the GII models are the Graph 75 and Graph 95. The Australian version of the GII is the fx-9860G AU PLUS.

S250 redirects here, for the genetic marker, see Haplogroup R-DF27. Pocket Viewer was a model range of personal digital assistants developed by Casio around the turn of the 21st Century. Pocket Viewer was a model range of PDAs from Casio. Early models used Intel x86 based processors. Models used Hitachi processors from the SuperH family. Both models ran Casio's proprietary OS'CASIO PVOS'; the functionality of the pocket viewers extended beyond the digital diary segment and targeted consumers who needed more compute power in their personal organizers. The pocket viewers competed directly with the market leader in the segment the Palm-pilots, they were priced under $200 at first release. The pocket viewers, weighing under 5 ounces, were portable; the face of the device was entirely covered by a monochrome liquid crystal display. Towards the bottom of the LCD there were a few navigation keys; the lower most part of the LCD had quick short cuts to the standard applications permanently indicated. The short-cuts include off, back-light, Contacts, Quick Memo, Sync Start, Menubar.
The standard applications available on the pocket viewer include Expense, PVsheet, Contacts, Scheduler, ToDo list, Reminder/Calendar and Alarm. The starting interface consisted of a scrollable two column list of icons. Clicking on the icon starts the application. Text was entered via an on-screen keyboard; the pocket viewer did not have in-built hand writing recognition support. A third party GPL addin PVMerlin may have attempted to provide hand writing recognition. Pocket viewers used conventional 2 x AAA batteries and under normal use a charged battery lasted around 2 months; when not being used the pocket viewer switches off the display and goes into power saving mode. The specifications stated that it could function for 50 hours on alkaline batteries without use of back-light. Except for PV-S1600 which used Universal Serial Bus 1.0, all the other pocket viewers used a COM port to communication between a personal computer and the pocket viewer. Casio made. Using the SDK users could create their own applications called add-ins, which could be downloaded to the pocket viewer using the synchronization software.
In time, a small user base who created and made their add-in applications available on-line for free or for profit emerged. User forums such as pocketviewer.de, pocketviewer.com, pocket-viewer.ru and pocketviewer webrings flourished in their time and have since closed. During 2005-2010, the second hand market was on the vane. OWBasic, a third party add-in, provided the easy to learn and use BASIC interpreted programming language on the hand-helds, expanding their functionality to being programmable hand-held calculators/computers; the device had the computer functionality as the home computers of the 80s. The pocket viewers ability to access the internet was limited. PC software could synchronize email with the device, not convenient; the device had a specialized serial port, could theoretically communicate with other devices using the Serial Line Internet Protocol and execute modem AT commands. Casio provided some additional applications. Enterprise Harmony, which enabled Outlook 2003 synchronization of Outlook contacts, calendar On windows.
PVsheet, a spread sheet application, which could upload/download comma separated spread-sheets. Travel phrase guide, which could translate preset text between English, French, Italian, Japanese; the Casio pocket viewer series was sandwiched between digital dairies and the pocket PC series Casio Cassiopeia. Casio discontinued the pocket viewers as the pocket PCs became popular and their price came down; the PV-100 did not have a back light. While the back light was available on PV-200 onwards, Casio by default did not allow the back-light to remain on more than 30 seconds. Casio did not recommend extending the duration of the back light citing battery drain; as A third party application back light extender add in was required to keep the back light on beyond the default duration. The back-light was Casio's trade marked EL-back-light, an electro-luminescent panel that causes the entire face to glow; the PV-S1600 did not use a NEC V30MZ processor, but used a Hitachi SH-3. The processor architectures are not compatible hence programs compiled for the earlier architectures do not work on the PV-S1600 without recompilation.
OWBasic programs will work. The NEC V30MZ was a 16 bit processor. An indirect consequence is that those models can download a maximum of 16 addins The file system is divided into PVOS modes and sub modes; each record is part of a file, specified by mode and submode. Depending on the mode data sets are null-terminated in either text format. Binary data sets are to 3 KB or 32 KB, text data sets to 2 KB; the PV-750 has an IrDA port. Using IrDA, it is possible to receive email messages using a GSM-enabled mobile phone. SMS can be sent on the PV-750Plus; the address book of the mobile phone can be synchronized with that of PV. Casio's operating system update for the PV-750 gives it the same functionality of the PV-750Plus; the HP 200LX a palm top computer used an 80186 chip The Casio ClassPad 300 is a maths orientated update of the pocket viewer. Casio did not provide any official linux support. Casio had contracted a 3rd party vendor for PC communication, hence could not disclose any internal communication protocols.
Apart from Casio PC sync and Enterprise Harmony, shareware Xlink/Win prov
An electronic organizer is a small calculator-sized computer with an in-built diary application but few other functions such as an address book and calendar. It has a small alphanumeric keypad and an LCD screen of one, two or three lines; because of the advent of personal digital assistants, smartphones in the 2000s and 2010s both of which have a larger set of features, electronic organizers are seen today. Casio digital diaries were produced by Casio in the early and mid 1990s, but have since been superseded by Mobile Phones and PDAs. Telephone directory Schedule keeper: Keep track of appointments. Memo function: Store text data such as price lists, airplane schedules, more. To do list: Keep track of daily tasks, checking off items as you complete them. World time: Find out the current time in any location on the globe. Secret memory area: The secret memory area keeps personal data private. Once a password is registered, data is locked away until the password is used to access the secret area.
Alarm Metric conversion function: Conversion between metric units and another measurement unit. Currency conversion function Game: Some machines included a game such as Poker or Blackjack. PDA Smartphone Pocket computer
The Casio SK-1 is a small sampling keyboard made by Casio in 1985. It has 32 small sized piano keys, four-note polyphony, with a sampling bit depth of 8 bit PCM and a sample rate of 9.38 kHz, a built-in microphone and line level input for sampling, an internal speaker. It features a small number of four-note polyphonic preset analog and digital instrument voices, a simple additive voice. All voices may be shaped by 13 preset envelopes and vibrato, it includes a rudimentary sequence recorder, preset rhythms and chord accompaniment. The SK-1 was thus an unusually full-featured synth in the sub-US$100 home keyboard market of the time; the SK-1 includes one pre-arranged piece of music, the Toy Symphony, played when the "Demo" button is pressed. The Radio Shack version of the Casio SK-1 is called the Realistic Concertmate 500; the SK line continued throughout the late 1980s, including the SK-2, SK-5, SK-8 and 8A, SK-10, SK-60, SK-100, SK-200, SK-2100. The SK-1 has been used by a few major recording artists for its lo-fi sound.
It became popular in the late 1990s among the circuit bending crowd after the first guide to bending it was published by Reed Ghazala in Experimental Musical Instruments magazine, though the SK-1 was being modified as early as 1987 when Keyboard Magazine published an article on adding MIDI support. The synthesizer was one of the first pieces of equipment that Autechre had when they began recording music. Musician and score composer Michael Andrews featured a circuit bent SK-1 in the Me and You and Everyone We Know musical score; the "Realistic Concertmate" version of the SK-1 is the primary synth used in the no wave / industrial band Special Interest. It was used by notable jungle artist DJ Hype for his seminal productions, rapper and producer Large Professor used it in his early years of beat-making. Owen Ashworth used and recorded with one for Casiotone for the Painfully Alone's second live album In Sydney. Mount Eerie's Eleven Old Songs of Mount Eerie consisted of Phil Elverum's vocals and an SK-1, making use of its various effects and built-in rhythm machine.

The Casio F-91W is a quartz digital watch manufactured by Japanese electronics company Casio. The original F-91W is still in production, it is popular for its simplicity and unpretentious clean design. Its design has not changed; the watch is available in several variants as part of the Casio F-series of watches. Casio does not release sales figures for the model, but admits it continues to sell "well". Annual production of the watch however, amounts to 3 million units; the F-91W has a 1⁄100 second stopwatch with a count up to 59:59.99. Marking net and split time is featured. There are a single daily alarm lasting 20 seconds, it has an automatic calendar, although auto-adjustment for leap years is not supported, as the watch does not record the year. February is always counted as 28 days; the watch uses a green LED light located to the left of the display for illumination. The watch is reported to be accurate to ±30 seconds per month by Casio; the watch is powered by a single CR2016 3-volt lithium button cell, which lasts at least seven years, assuming 20 seconds of alarm and one second of light usage per day.
However, these are used in practice, so it is not uncommon for the battery to last 10 years or longer. The watch case weighs 21 grams; the manufacturer's module number for this model is 593. The strap is 22 mm across the widest part of the lugs; the watch has a rubber seal between its steel back and case, but does not have any seals for its buttons. Since they fit enough, surface tension prevents water from getting inside, but only to a certain point of water pressure. Therefore, the watch front is marked WATER RESIST, but Casio reports different values for different variants of the watch; the black version is "30 meter / 3 bar", the ISO standard meaning of which is: "Suitable for everyday use. Splash/rain resistant. NOT suitable for showering, swimming, water related work and fishing", but the colored versions are "DIN 8310 / ISO 2281 – resistant to minor splashing". Though the resin strap version will resist an occasional water submersion if the buttons are not pressed, the watch should not be used in such conditions on a regular basis.
The watch is known to be durable. The body of the watch is known for lasting longer than the 10 year battery life; the watch will outlast the plastic strap that it comes with. Casio replacement straps are about the same price as a new F91W watch, however there are replacement straps from other sellers available at a fraction of the cost of the original ones. It's common to buy a cheap lookalike and use that strap; the watch is controlled by three side-mounted push-buttons. The upper left button turns on the light, cancels the alarm, resets the stopwatch or marks the split time, is used for selecting settings; the lower left button cycles the modes of the watch: time display, alarm and time/date adjustment. The button on the right is the function button: when used, it starts and stops the stopwatch, changes the settings being adjusted, or switches between the 12- and 24-hour modes, depending on what mode the watch is in. Pressing all three buttons at the same time will fill all the cells on the LCD until any button is pressed again.
The time or date is adjusted by pressing the lower left button three times to bring the watch to time adjustment mode. The top left button is used to cycle through seconds, minutes, date and normal mode; the right button is used to adjust the flashing value displayed. Unlike any other value, the seconds can only be zeroed. Should this happen before 30 seconds, the watch will zero in at the beginning of the current minute. After 30 seconds it will start the next minute as displayed; when the adjustments are finished, the bottom left button can be pressed once to return the watch to normal mode. The watch display shows the day of the week, day of the month, minute and the signs PM in the afternoon – or 24H – at all times, the alarm signal status, the hourly signal status are present when activated in the alarm mode. In stopwatch mode, minutes and hundredths of a second are shown. According to secret documents issued to interrogators at Guantanamo Bay and released by The Guardian, "the Casio F-91W digital watch was declared to be'the sign of al-Qaeda' and a contributing factor to continued detention of prisoners by the analysts stationed at Guantanamo Bay.
Briefing documents used to train staff in assessing the threat level of new detainees advise that possession of the F-91W and the A159W – available online for as little as £4 – suggests the wearer has been trained in bomb making by al-Qaeda in Afghanistan." United States Military intelligence officials have identified the F-91W as a watch that terrorists use when constructing time bombs. This association was highlighted in the Denbeaux study, may have been used in some cases at the Guantanamo Bay detention camp. An article published in the Washington Post in 1996 reported that Abdul Hakim Murad, Wali Khan Amin Shah, Ramzi Ahmed Yousef had developed techniques to use available Casio digital watches to detonate time bombs; the watch is worn all over the
Casio digital horn
The Digital Horn was an instrument produced by Casio in the mid 1980s. The original model was presented as either the DH-100 or DH-200; the rare DH-500 was a larger instrument with additional keys for semitone down and octave down, plus switches to enable or disable vibrato and reverb. A model, DH-280, was the same instrument with an added "accompaniment module.' This module was carried into the DH-800: a cartridge insert provided four pre-recorded songs. These songs consisted of When the Saints go Marching In,Air on the G String,Chopin's Nocturne, I Lost the DOH in my Clarinet, each of which could be played with or without melody; the module provided sixteen standard rhythms. Each model has six built in synthesized sounds; the tones produced. The Digital Horn looks like a clarinet/saxophone hybrid, can be played with recorder-like fingerings over a two-and-a-half-octave range, or with the "Casio system" which allows for up to 4 octaves to be played. Unlike any acoustic woodwind, there is a universal semitone-up key operated by the left pinky.
The left thumb operates a sax-like octave-up key. A'transpose' button permits the player to change to any chromatic key over a two-octave range; the DH-280 has a tuning button. A key near the top of the instrument allows a portamento-like slide between notes. A switch permits the instrument to be played without blowing through it, making the keys operate like a digital keyboard; these instruments were breath-sensitive for volume. Unlike other digital wind controllers, the breath flows through the instrument, making it feel similar to an acoustic woodwind instrument; each came with a small built-in speaker, had an output cable for external amplification. MIDI OUT capability of the instrument means that it can be used to control sounds from other MIDI synthesizers that offered a MIDI IN connection; these features, as well as the low price, increased its appeal to budget-minded musicians. Power for the instruments came from five AA batteries, with provision for connecting an aftermarket 7.5 volt AC adaptor.
The instruments are prone to developing a squeal. This is because of a capacitor deteriorating. None of the instruments had a read-out display of any type, so transposing, changing tone, other functions required counting button-clicks; the Digital Horn transmits initial breath pressure as MIDI note-on velocity, subsequent breath pressure changes during a sustained note as channel after-touch, portamento on/off as CC 65 with values of 0 and 127. This instrument was most notably used by The Elephant 6 Recording Company based in Athens, Georgia and by Was in live performance of I Feel Better than James Brown. Notable in the intro to album cut "I Blew Up the United States." The term "zanzithophone" is used to describe the Digital Horn inside the inlay for Elephant 6 band Neutral Milk Hotel's album In the Aeroplane Over the Sea, which featured the instrument, in a footnote on page 66 of Kim Cooper's book with the same title about the album. Other than these two references, no one else calls the Casio DH Series horn a "Zanzithophone."
