Saraah: FIRST. clean the VCR heads and tape path including guides and rollers with special attention paid to the AC head, capstan and pinch roller. Try a different or a new tape.. the tape is possibly edge damaged which would cause problems for the VCR reading the control track signal. If this happens with ALL tapes, then look for a worn pinch roller. worn capstan bearing or bent loading arm that could cause the tape to ride up or down on the A/C head while playing.

Acer, FIC, and Mitac Dont Bring Home the Bacon
Well, there any number of schools of thought on whats going on with the economy, from the idea that everything has tanked, to a sort of Darwinistic idea that after the weaklings are weeded out, everything will be fine (the latter is a little extreme, but Ive heard itjust dont believe it). How you view the current economy is extremely subjective and how you view this next bit of news from DigiTimes will be too. According to the site, Taiwans three major PC system integratorsAcer, FIC, and Mitacare running behind and will need 40-50% growth in monthly revenues over the next half of the year to meet their revenue goals. FICs revenues in June reached NT$3.655 billion, falling 31.33% from the same month of last year, while Mitac posted revenue of NT$2.340 billion in June. FIC would need revenues of at least NT$5.7 billion every month in the second half (42.5% more than in H1) to achieve its goals. Mitac will need monthly revenues to grow 55% from the first half to get where it wants to be. Now, whether you see the glass as half full or half empty will depend other whether you think everyone was surprised by the economic slump (ie: was too optimistic in their forecasts), or that the tech world is financially going to hell in a handbasket. All opinions are always welcome.
Another year has passed and the US is celebrating its independence from the British Empire, won in 1776, once again. I wish every American a lovely and relaxing day, and try to have a look at the role of the word 'independence' in the computer industry today.

First Look At Brookdale Intel's Upcoming 845 Chipset
Pentium 4 sales remain low, which is not entirely the fault of the price/performance of Intel's flagship processor. Current i850 platforms require Rambus' expensive and unpopular RDRAM, which reduces Pentium 4's appeal to the buyers even more. Soon Intel will come up with an alternative to i850 plus RDRAM. In a few weeks we will have the chance to spend our money for an even crazier solution. The i845 chipset will team up Pentium 4 with the slow and ageing PC133 memory. We tested this bizarre combination. June 12, 2001

900MHz Xeons Are Hot (Not a Cool Thing)
Last week we heard a rumor from over at The Inquirer that 900MHz Xeons were exhibiting bad thermal problems. Mike Magee has his ear to the ground for such murmurings and darn if his suspicions werent right on the money this time. In a story today, The Inq let us know that Intel has officially confirmed that the chips run hot. While Intel says that the problems with the chip only occur on processors with 2MB of L2 cache, justice has been done, and Intel wont be shipping any more of the little devils until August. If you cant wait, Intel will be happy to replace the chips with 700MHz processors. What kind of deal is that?

We all know that Compaq has pretty much transferred its Alpha division over to Intel, but not much has been said about support for current Compaq Alpha users. Sensing that these folks may be feeling a bit abandoned, Sector7, a company that specializes in UNIX to UNIX migrations, and IBM have announced that they will be offering Compaq VAX/Alpha OpenVMS and Tru64users a free initial assessment to determine cost and time to re-host their custom or package applications to IBM pSeries RS/6000 computer systems. This type of consultation usually isnt cheap, but the offer from Sector7 and IBM will eat consultation costs of up to a $100,000 depending on the application size. Jon Power, president and CEO of Sector7 USA is quoted as saying "Alpha OpenVMS and Tru64 UNIX clients have invested millions of dollars in applications to run their businesses and I doubt they ever thought that being forced to migrate to a totally new computer system was what Compaq meant by protecting their investment in Alpha platforms." Ouch, pretty strong words. The philosophy here seems to be that if users dont want to eventually move over to an Intel architecture, IBM will happily let them know how much it will cost to switch over to its products and even hook them up with people who can help them do it. You can bet the next step will be discounted prices for those who seek to switch teams. Sector7 services include enterprise application re-platforming, legacy application management, OpenVMS consulting, support and contracting, testing and implementation, application renovation, and server consolidation and migration. Though we certainly have absolutely no idea how good these folks are pulling off these feats, thats basically the whole ball of wax aside from buying the machines. And a damn smart business move.

At The New Pentium III (Tualatin or Coppermine-T?)
Somehow one of those new Pentium III (Tualatin or CoppermineT?) processors with the famous clock speed 1.13 GHz happened to fall in our lap. We think that for historical reason it should be us and nobody else, who tests Intel's second attempt to manufacture a Pentium III at this clock speed, so we gave the still 'secret' chip a good test run. Now we understand why Intel doesn't know if it should release it or not. Once overclocked to more than 1.4 GHz it is able to threaten Intel's fastest Pentium 4 processors.

Photo-Sharing For Your TV Feedback
Eastman Kodak and LSI Logic are going to make it possible for you to annoy your visitors with a slide show of your summer vacation on your television. The agreement, originally signed by LSI Logic's recently acquired C-Cube Microsystems, will allow you to view digital pictures from a Kodak Picture CD directly on your TV (without a computer) using your DVD player. New features added to the LSI DVD players will include automatic picture scaling to fit the TV display size, slide show capabilities, one-screen thumbnail display, and image rotation. The whole thing may sound trivial at first glance, but this is the kind of little thing that will help move DVD players and set-top boxes into the homes of the tech-wary masses. At the same time, it could make digital cameras a heck of a lot more popular with folks that dont have computers and let the less technologically challenged send digital pictures (on a disk) to those who havent embraced the wonders of the digital world.

Hitachis Skinny New 21-Inch Monitors

If you cant wait for affordable large LCD displays to hit the stores, Hitachi and other companies are building monitors that may be a compromise that still helps you save desktop real estate compared to that behemoth thats taking up your whole work area. Hitachi has just added three new 21-inch monitors to its 3S Series of Super Space Saving displays. The new CM827, CM828 and CM828B displays measure 18.5" in depth and weigh only 60 lbs. The dot pitch for all three of the new monitors is 0.21 mm horizontal and 0.14 mm vertical. The CM827 provides resolutions up to 1856 x 1392 at a 72 Hz refresh rate, while the CM828 and CM828B models give you resolutions up to 2048 x 1536 at a 71 Hz refresh rate. The CM828B is the same monitor as the CM828 in fancy black cabinet. All three (really two) models feature language selection and on-screen controls with adjustments for color temperature, degauss, moire, pincushion, etc. They also have dual inputs so you can switch between two computers without re-booting. Pricing for the CM827, CM828 and CM828B ranges from $779 to $849. Tempting, but Ill probably wait for a flat panel.

Streaming Live Multicasting Ready for the Wires
Multicast Technologies announced today that their company is offering commercial streaming solutions for multicasting live events from remote locations. The company is now licensing this patented technology to companies interested in delivering audio and in the very near future near-broadcast-quality video. Right now, Multicast offers live and prerecorded webcasts as well as pay-per-view events through the use of multicasting. Multicasts testbed audio station, On-The-I.com has been letting musicians multicast live from concert venues in the Washington, D.C. area. Live streaming audio doesnt sound all that groundbreaking. I can listen to a gazillion different radio stations and can hear the announcer (talking live) just fine. Broadcast quality video would be much cooler, enabling you to watch a ball game or a live music event online. Right now, even streaming recording video tends to be a bit herky-jerky. Apparently, Multicasts system conserves bandwidth by only streaming when a user requests it. In other words, it doesnt send out a flood of data waiting to be diverted to different locations, but conserves bandwidth by only sending out what it needs to specific locations.

SONICblue Picks up Sensory Science
http://www.tomshardware.com/technews/technews-20010710.html (3 of 5) [7/16/01 11:56:32 AM]
SONICblue, which used to be S3 until it acquired Diamond Multimedia in 1999 and moved into building Internet appliances, broadband communications, home networking, and audio gadgets, just completed its acquisition of Sensory Science, a digital entertainment company specializing in developing digital video and audio products. Sensory Science products include the Go-Video DVR4000 DVD/VCR combo unit, (which actually doesnt sound like a bad idea for a conversion device until DVD-R/RW gets more affordable). Sensory Science also builds digital televisions, Internet media players, DVD players, and home theater components. Interesting to see what all those ex-graphics card companies are evolving into, isnt it?

Freebie IBM XML Registry Tool and Utility Services
IBM apparently wants XML standards so that XML becomes more of a standard. Last week, the company put forth a new free extensible XML resource on its alphaWorks site that it says lets developers store, search, and manage XML-based applications. Using the tool, IBM says developers can manage their XML schemas (DTD, XSD), stylesheets (XSL), and documents (WSDL) with the new XML Registry/Repository (XRR) data management system by downloading XRR from the alphaWorks site. The tool lets end users search or browse for an XML document or schema, then insert the document into their application. XRR lets IBM's DB2 Database store and search XML documents by content, including tasks like registration, searches by metadata, classification, and association. XRR is an implementation of the OASIS XML Registry Working Draft Specification 1.1. The alphaWorks site is also offering free utilities and a new subscription model for online applications. From what I read, alphaWorks utilities are a prototype of a network-based computing service model that is supposed to let customers subscribe to services purchased on a measured unit such as time, capacity or throughput. IBMs first Utility Service will appear as a trial download on alphaWorks, and is a Publish/Subscribe Message Brokering (PSMB) system. PSMB middleware supports the routing of information via streaming events from information providers to information consumers. Remember that alphaWorks is a setup where you download apps and such before they reach prime time. The theory behind it seems to be that by putting stuff out there, it will get batted about by developers, hence getting the finished products to market sooner. Kind of a Play Before You Pay model, but with your input, the end products are (theoretically) more likely to contain features that you want to see. Im sure those in the know will clue me in.
