Alcatel looks forward to retro-styled 'vintage' slider

12:36 AM


Dubbed the OT-C825 Vintage Slider, it's anything but old fashioned: the handset has dedicated music playback keys; a 176 x200, 262,144-colour display; Bluetooth 2.0 with A2DP wireless stereo technology; and a six-hour talk time.

The camera's resolution is a little behind the times - it's just 1.3 megapixels - but it'll work as a webcam if the phone's connected to a PC's USB port.

Perhaps it's the phone's "smokey brown" colour scheme that gives it that "vintage" feel? It's certainly got a dour, retro quality to it reminscent of bakelite radios and their ilk.

The OT-C825 comes with a 128MB MicroSD card for song storage. It's a tri-band GSM device.

Alcatel said the phone will go on sale in the June/July timeframe, but it didn't say how much the Vintage Slider will cost.

Mitsubishi HC5000BL projector

12:20 AM


Mitsubishi projector HC5000BL
"We have the latest technology, the latest features, and the highest quality performance available today." The HC5000BL is designed with new inorganic LCD panels that are more durable and provide a more color-consistent, even-toned image than previous generation LCD panels. The LCD optical engine is enclosed to prevent dust from entering the engine, which decreases the number of particles landing on the LCD panels, and keeps the image cleaner. Mitsubishi's HC5000BL delivers HQV through Silicon Optix's Reon-VX chip, which provides true HQV four-field, motion-adaptive, per-pixel, high-definition (HD) deinterlacing that delivers the sharpest and most detailed HD images possible. The HQV multi-direction diagonal filter removes any "jaggies" and/or stair-step artifacts from deinterlaced video sources without blurring the image, while sophisticated noise reduction technology removes the noise and artifacts caused by compression.

Mitsubishi projector HC5000BL - Details
Using Mitsubishi's exclusive algorithms to control its dynamic iris, the HC5000BL also boasts one of the highest contrast ratios available today, achieving an unprecedented 10,000:1 for the most exacting features in dark areas of an image. These new algorithms detect and maximize color information as well as luminance, creating realistic detail in film noir and action flicks. With up to 5000 hours of lamp-life (in low mode), HC5000BL owners won't have to change them often, but when it's necessary, the new projector offers a design that makes replacement quick and easy. Through an easily accessed lamp housing, users simply switch the lamps without taking the mounting structure apart and physically handling the projector.

Intel 8087 family

12:06 AM


Intel 8087 is a numeric co-processor for Intel 8086, 8088,80186 and 80188 processors. The 8087 has 8 80-bit general registers implemented as a stack. All floating point operations are performed with data from the stack (usually the data at the top of the stack) and data from external memory. Effective address calculation for external memory accesses is performed by the main processor. Both the main processor and the 8087 decode floating-point instructions (they all start from ESCAPE bit pattern). If the decoded instruction references the memory then the main processor calculates memory effective address and performs "dummy read" of memory. The Intel 8087 captures the memory address and, possibly, data, and uses the captured address to read more data or write data to memory. After that the main processor may continue to execute integer instructions without waiting until the 8087 completes execution of the FP instruction. To synchronize execution of multiple FP instructions the main processor used WAIT (FWAIT) instruction to wait until the co-processor becomes available. Because the integer instructions and floating-point instructions could be executed in parallel, it was common to see integer and FP instructions intermixed in x86 programs.

Intel 8087 co-processor supports integer, BCD, single and double precision floating-point numbers, as well as extended precision (80-bit) floating-point numbers. When the 8087 loads data from memory it always converts it internally to extended-precision number, and all further calculations are performed with this number. This is why switching from double to single-precision number or from 64-bit integer to 32-bit or 16-bit integer numbers doesn't provide any significant performance boost.

Intel was not the only manufacturer of this co-processor. AMD and Cyrix Corporation both produced 8087 co-processors. Soviet Union produced clones of 8087 FPU. There are 8087 co-processors stamped "IBM", but it seems that IBM Corporation didn't manufacture the chips and only re-branded Intel chips.

WHAT TO LOOK FOR WHEN PURCHASING AN IBM MODEL M KEYBOARD

11:53 PM



The IBM model M keyboard is that rare piece of computing technology which is both a vintage collectible item and also a useful tool in today's computing environment. IBM model M keyboards are unique in that each one is individually labeled with a serial number and the "date of birth" is printed on the back. They were first built in 1985 and were produced through the 1980s and 1990s, until 1999. Under each keyboard key there is an individual spring that when compressed converts physical force into an electrical signal. Most modern "free with purchase" keyboards used cheaper rubber-pad based technology. In addition, inside each model M keyboard is a steel curved plate for durability while providing a slight ergonomic curved angle to typing. The individual key tops are removable for easy cleaning or for switching the format of the keyboard for different input languages Finally, the lettering on each individual key is physically molded and integrated into the plastic key top (not painted on or a sticker, like on cheap keyboards). If you have made the decision to purchase your first vintage IBM model M keyboard to replace your existing lowest-cost-to-produce / disposable keyboard, there are a few tips on how to select the best keyboard. There are a number of variants of the IBM model M keyboard. Most people are looking for the original IBM extended keyboard with 101 keys, with the model # 1391401 with a standard PS/2 plug on the end of the keyboard cable. These keyboards either have the IBM logo in black text on white background, or (a smaller number) blue text on gray background.

CDMA technology

7:07 PM


The latest technology being used in mobile communication is Code Division Multiple Access(CDMA). The communication technology has improved vastly over the last decade. Starting from Time division multiple access(TDMA) and then moving on to frequency division multiple access(FDMA) and then now we have code division multiple access(CDMA). All these technologies have helped in bringing more users into the system. Now most of the Phones support CDMA technology although it is not yet used in all parts of the world. It is a method that is being utilized by many radio communication technologies. Slowly it is now being used in mobile communication too.In mobile technology it is referred to as CDMA2000 OR cdmaone. In mobile communication, CDMA is the basic technology that is being used to send voice, data signals. There are various CDMA2000 standards that are being used and the basic one being 1xRTT.
