Jon, you're kidding right? Maybe it's true...someone told me the word "gullible" isn't in the dictionary. How could this device *work*? I have a sophomore knowledge of electronics and I could'nt figger this out. Peter np: Tear Ceremony: Resin ( review on the ambient list )

Actually Peter, some guy in Europe has done this. I didn't save the article (it went straight to my "eh whatever" bin), but apparently it is something real. He hooks up turntables & mixer to a AtoD convertor, plugs the digital stream into a BeOS computer, which has software that interprets the signal coming off of the vinyl. As for how one might do it, think about how modems work -- frequency shift keying in a limited bandwidth. You can encode position information onto the vinyl record as a modulation of a continuous tone. By figuring out the frequency of the carrier tone, you know how fast the record is spinning. By reading the position code, you know where you are on the record. To handle backspins, you encode the position codes in a frame of unique bit patterns, so you can read and decode a position code forwards or backwards. I've done low level data communications programming so I know this will work, pretty much. Whether it will work if you bump the stylus or get your special records warped and scratch is anyone's guess. For that matter, modems only work most of the time -- they ain't 100%.

yeah... well none of this sounds impossible.. it's just not practical.. first off, what the hell is a BeOS computer? :D I've never heard of it, and I'm a CS major.. but I'm just curious about that.. but would you be able to run two of these vinyl-data things on one of those computers? if not, someone would have to have two BeOS computers (which sound like either mini's or mainframes? if they were pc's I think I would've heard of them) and then 2 of these gizmos.. although this is quite interesting. __ __\ \ / /_\ \ \_____/ "..in whatever you do, if you can't break new ground, what's the point?" - James Cameron

BeOS is a mac OS. it looks pretty bitchin, as far as multimedia mac OSes go. .Bil. IAMaCOPIER

It's available for both PowerPC and Intel platforms. And bitchin is an understatement. -Michael

BeOs and the BeBox are done by Be Computers. Check out www.be.com. Be is a fantastic OS and hardware platform, which was designed from scratch with Multimedia in mind. -hjw

If you're using an actual Be Box, don't they have the Geek Port, which is analog?

Macs, right.. I know what the BeBox is.. a lot of Amiga fanatics were following it up really close hoping it would be "The New Amiga Sensation" .. and I remember BeOS as well.. but only when I heard BeBox.. if it's an OS ppl shouldn't refer to it as a computer :P __ __\ \ / /_\ \ \_____/ "..in whatever you do, if you can't break new ground, what's the point?" - James Cameron

Well, strictly speaking, it's not a "MacOS"... Be was a company founded by Jean-Louis Gassee, formerly of Apple Computer, about four years ago. The BeOS is their attempt to build a next-generation "multimedia" operating system, specifically tuned for video/graphics/audio work. In 1995 Gassee offered Be for free to Apple, saying that their Copland/MacOS 8 project might fail and thus they might want a back-up. Apple refused, but Copland was eventually cancelled in late 1996. BeOS was intended to run on the "CHRP" (Common Hardware Reference Platform) platform which initially was to include, running on the PowerPC chip: Solaris, Copland/MacOS 8, OS/2, Windows NT, AIX, BeOS. Most companies who signed on were just hedging their bets against Intel losing a lead in the microprocessor race... at the time some people were predicting the Pentium/x86 couldn't get past 90 MHz!! Proven wrong, the whole concept fell apart, leaving Apple and Be as the only CHRP supporters... Late 1996. There are several Apple cloners, BeOS is able to run on most of these machines in spite of the lack of true CHRP availability. December 1996: Apple buys NeXT computer thanks to the fancy footwork of Steve Jobs, over Be, who was rumored to be Apple's real target for months. OpenSTEP, NeXT's OS, will soon become MacOS X in late 1999. Meanwhile, Apple kills cloning and returns to a closed platform because, hey, no other OS vendors will support CHRP: IBM basically kills OS/2 just as it's finished in a war between its Intel-powered personal computer unit and its PowerPC-backing server unit (you can still order it, apparently), Microsoft won't port NT 5.0 because IBM and Motorola refuse to foot the bill (although NT 4.0 is available), Solaris never materializes, AIX runs on its own proprietary subset of PowerPC machines. So Be recently ported its OS to Intel-platform computers. Go to www.be.com... you can buy the DR or even download it. And like I said, yes, Virginia, it now runs on Intel machines... ______________________________ Reply Separator _________________________________ Subject: Re: (idm) MP3 from a turntable...
