Contents.fx-9750G Power The back of the device shows a slightly protruding battery case cover, which slides out to reveal the compartment for the four used for primary, and a button used for memory backup when primary power is down or being changed. The device consumes power at the rate of 0.06, and turns itself off automatically after about 6 minutes of time spent without any keypad activity. Battery life for the primary power cells ranges from 300 hours (LR03 battery) to 200 hours (R03 battery) for continuous display of main menu. Backup cells last up to about 2 years each.The calculators weigh about 190 grams including, and measure about 19.7 mm x 83 mm x 176 mm. Features include scientific, including, and, and operations.Display The display has a of 127 by 63 (the first row and column of pixels are unusable in graphing), and a character resolution of 21 columns by 8 lines. The bottom line is reserved for tips, and the rest is available for the graphics and character display.Memory The calculators includes program capacity of 26.

This is divided among storage blocks for programs, statistics, matrices, lists, static and dynamic graphs and their associated settings, functions, and variables (all of which are global). These can be cleared individually or completely in the MEM menu.When saving files, a file name uses 17 bytes of memory.A command consumes 1 or 2 bytes.Graphing Graphs can be drawn with split-screen viewing of graphs as well as tables. Graphed areas can be in customizable colors.

The graph can be resized and shifted (these settings can be saved for later retrieval), and points along the graph can be traced. Graph solver tools can also be used to find useful points, such as and intersection points. The calculator also has a special section for advanced graphing. Dynamic graphing provides all the functionality of regular graphing, but allows the binding of a variable in the graph equation to over a value range.Lists and tables Up to 36 lists can be stored and manipulated in various ways in the list manager. The lists can also be used to feed data into inbuilt statistics operations, producing various statistical figures, performing, and generating graphs like and, among others.

Can be generated from, recursive series can be generated, and equations can be solved - both and polynomial.Communications The device can link up by cable to a computer (FA-122 and FA-123 (serial) and FA-124 (USB) interface unit and cables) or to another calculator (SB-62 cable) to transfer data, such as programs, equations, graphs etc. It can also connect to a Casio (SB-62 cable).

Transmission speed is stated as 9600. The calculator can be connected to the EA-100 data logger which is used to read data such as temperature, light intensity, force, voltage, loudness, pH and other such data in the same fashion as the Texas Instruments Computer Based Laboratory and various data loggers for use with the Hewlett-Packard calculators; Sharp also makes such a tool.The serial link cable was designed and U.S. Patented (5504864) by Larry Berg of Purple Computing. It was manufactured by Traveling Software (AKA Laplink.com) and later by Purple Computing for Casio. The common name for the cable used by the companies was 'PC-Link'.

It has a 2.5mm stereo phono plug on one end, the patented electronic circuit inside the plastic bump and a on the other for connecting to the serial port of a PC. The circuit converts low voltage low power signals of the handheld device to be compatible with the levels and power of a PC's serial port. Casio CFX-9850GC PlusCFX models are capable of displaying three:,. The colors are handled much like a multi-level grayscale display, in that altering the contrast of a pixel changes its color. A light contrast displays orange, then as the contrast increases, the color becomes blue, then green at a dark contrast.Memory The calculators include program capacity of 28 to 64 of memory depending on model:.

fx-9750G PLUS: 28,000. CFX-9850G PLUS: 30,000. CFX-9850GB PLUS: 30,000. CFX-9850GC PLUS: 61,000. CFX-9950GB PLUS: 61,000Software Library The CFX-9850GB PLUS and CFX-9950GB PLUS models have a built-in, consisting of programs that perform complicated calculations.

For example, operations on, measurements, charge curves,. These are organized into six sub-libraries, five of them for mathematical, and one for scientific.Financial calculations A number of financial operations such as and are also provided.CFX-9970G. Casio CFX-9970GChanges from CFX-9950GB PLUS include:.

CAS (algebra mode), it is the first Casio calculator to include CAS, and the first calculator with color screen and CAS. The algebra mode can perform a lot of symbolic manipulations, like expand, solve, derivatives, integrals (definite or indefinite), etc. In the algebra mode, the output is shown as natural screen, feature later included for input or output in modern calculators like fx-991ES. Reduced power consumption to 0.2 watt. Battery life for the primary battery ranges from 230 hours (LR03 battery) to 140 hours (R03 battery) for continuous display of main menu. Revert to the use of rounded rectangular buttons in all except direction keys.

A single elliptical pad replaces all 4 separate direction keys. Software library is not included. The calculators includes program capacity of 60 of memory.Trivia According to the, the calculator scores at 0.000027 BogoMips. It uses a Hitachi HCD62121 CPU custom-built for the Casio 9850 series.

While I'm not exactly sure where to put this. I've always wanted one of these. It came as a complete shock to me tonight to realize that the guy who started this site is the designer of the uWatch. I couldn't understand why manufacturers don't seem to be interested in developing a new scientific calculator watch.

I know, I know. There are a few of them available, but they're high end.

What I loved about Dave's methodology in presenting his design was the concept of 'you want something like this that badly? Build it yourself.' I really wanted one of those kits and even sent him an email about them (this is quite a long time ago, of course, when he was presumably less busy), and he told me that he'd moved on from it. Obviously, he has.

My question to you is this: How many of you would use (were it readily available) a wristbound calculator with all the functions you'd expect from your scientific pocket calculator, or your phone app moonlighting as one? Am I alone in imagining that there's a hole that needs to be filled here, and not just the one in my mouth for my shoe to fit into? My point exactly. Certainly this thing could be more cheaply manufactured now.

That's why I don't understand why no one has jumped into this niche. I'd like to respectfully ask the moderators, considering my regrettable lack of foresight in the matter and relative novelty around here as a posting member of this forum, to consider moving this thread to a different section where we might get a larger sampling of views from forum members (for example, 'Products' or even 'General Chat'). I ask this because A) I'm not at all certain that a discussion of a discontinued calculator watch (or, especially, petitioning for a future model!) necessarily belongs in the 'Vintage Computers' section, and B) because I feel strongly enough about this topic that I'd like more people to notice the option to weigh in with their opinions and information.

Sign me up for one watch and one FX-61F There is the possibility of repurposing HP's calculator line as it's just an ARM7: Edit: the new FX-991 EX is pretty good. You can turn off all the shitty entry functions and use it as an engineering calculator.

Has solver, engineering units, conversions, constants, base-N and the display isn't shit. If they do a programmable one I'm going to be all over it like a seagull on chips. Edit again: For ref, the OEM for most of the calcuators from Casio, Sharp, HP, TI etc these days is Kinpo.
