Welcome to Cemetech! Since 1999, Cemetech (pronounced KE'me'tek) has been developing software and hardware in many technology-related fields. Among Cemetech's specialties are TI graphing calculators such as the TI-83+/SE and TI-84+/SE, the Casio Prizm graphing calculator, web programming, and DIY hardware projects and modifications. Kerm Martian, né Christopher Mitchell, has since 2004 held the title of the world's most prolific graphing calculator programmer, with over 400 completed programs and more than 900,000 direct downloads. He has also developed many software and hardware projects. As an active webmaster and developer, you can often find him idling here in Cemetech's SAX chatroom.

Unlike the downtime we unexpectedly encountered shortly after March, which was user error, our server host has found a possible defect with the PSU with either our server or this model of server we use. That maintenance is scheduled to happen between 11pm on May 27th to 6am the following day, the 28th, New York local time; roughly (late) Monday evening for the the users in the US and around Tuesday early afternoon for those in or around Europe.

Two weeks ago, Cemetech interviewed the Education Solutions Architect at HP, GT Springer, to pick his brain about HP's new Prime graphing calculator. Due in stores this fall, the HP Prime represents a significant refocusing of HP's efforts towards the educational market, especially high school and college students. At the same time, the Prime represents a modernization of HP's calculator hardware, matching the Casio fx-CP400 with a (multi-)touch screen, and the TI-Nspire and TI-84 Plus C Silver Edition with a 320x240 color LCD. Among the most common questions from Cemetechians are what hardware the HP Prime will sport under the hood, and what graphs from HP's supposedly powerful new graphing utility look like. We're happy to be able to provide new information on both.

The specs we learned are probably not in as much technical depth as you all might want, but they do confirm much of what we suspected already and provide a few additional details. If you want to peruse them yourself, we have the full datasheet available. It confirms that the HP Prime will have a 400MHz ARM of unknown provenance, a 3.5" multitouch 320x240-pixel 16-bit color LCD, and an alphanumeric keyboard. The calculator's body will be 7.1 inches tall and 3.4 inches wide, with a TI-Nspire-esque 0.6-inch thickness. It will weigh in at 228 grams, or almost exactly half a pound. It will use a rechargeable Lithium Ion battery that charges via the microUSB communication port; no information is available on how many hours of usage that battery will give you. One additional interesting tidbit from the datasheet is that the calculator will come with both the connectivity kit and an emulator right out of the box, a notable departure from TI's official emulators, which we believe are generally priced around the cost of the hardware handheld. Casio seems to take a middle ground, offering a 3-month free trial period of its emulators.

Our appreciation goes to HP for sharing this new information with us. We hope it gets you thinking about the state of the art in the still rapidly-expanding set of available graphing calculators. We have yet to get our hands on the fx-CP400 and the rumored (possibly touchscreen) TI-Nspire CX Premium calculator for comparison, but from what we know, I for one am looking forward to giving the Prime a try. Check out the screenshots HP provided from the Advanced Graphing App in the topic for this news, along with associated equations where available.
