Well, I don't respond well to personal attacks, character assassinations,
juvenile exchanges--I really just don't have time--nothing to be gained really--but, if you must, proceed at your desire... rec.radio.cb has made me aware of such exchanges on newsgroups--and thickened my skin... grin John -- Sit down the six-pack!!! STEP AWAY!!! ...and go do something... wrote in message oups.com... | From: "Michael A. Terrell" on Wed,May 11 2005 9:50 am | | John Smith wrote: | | So, although your original argument was how difficult a bus and | keeping | analog seperate from digital which would share various | signals--would be, | then, when the argument was made that someone just picked up a bunch | of | on-the-shelf items and went ahead and done it... you flip-flop--to | where now | it was so obivious someone should have done such a simple thing LONG | before | them... | | I didn't "Flip-Flop" I know what's involved, including the million | dollar plus expense involved in designing one configuration of a | modular | radio. | | Michael, don't let this POSEUR bother you. That | anony-mouse "John Smith" hasn't been there, hasn't | done it. He wants to be "Instant Guru" and wants | a "rep" without doing any work for it. From what | he states - all in generalities, no specifics - | he can't think things out close to necessary detail. | | You were right to "plonk" him. | | | You have your head up your sorry ass, and I'm through wasting time | with your nonsense. Its obvious that you don't know a dam thing about | design when you compare the Apple II to a real design project. You | need | to get an education in design and stop trying to blow smoke up | everyone's ass. | | Way to go! :-) | | At some other time I wouldn't mind having a friendly | argument with you on the Apple ][...but not with this | anony-mouse hanging around trying to intrude and | smoke up the place. I still have my 1980-purchase | Apple ][+ and had a lot of fun with it...including | lots of calculations (Applesoft had 10-digit | accuracy with 5-byte FP variables, muy better than | 4-byte single precision). I've gone into the hard- | ware and analyzed it thoroughly, scoped it, written | it up...submitted it as a manuscript only to find out | Howard W. Sams was already in production on a similar | book! :-) | | In many ways, the PRODUCTION version of the Apple ][ | was the forerunner of the IBM PC out of Boca Raton. | But designed (or rather re-designed) about two years | prior to the IBM PC. Uncanny similarity between the | two in basic structure, expansion slots, and - yes - | "open architecture." PRODUCTION planning went into | the ][ and it wasn't much like the original board- | only Apple. | | But, the ][ on up to the Apple //gs were terrific RF | generators! :-) By contrast, a similar structure | using only three main chips (CPU from Western Design, | 64K EPROM, 64K/128K Static RAM) can be very nice and | quiet RF wise because of the internal transistor | structures in those chips. [I've already done a | preliminary breadboard setup to verify that] Such a | controller system can adapt itself to many kinds of | "radio controller" applications without any of the | RF coupling problems. It's been done before by the | big three in Japan using older microcontrollers in | many different transceivers, all without disturbing | the receiver or the transmitter specifications. | | Too many of the older hams are oriented towards a | "legacy radio" structure...mostly analog. That | just doesn't adapt to "plug-and-play" ease of adding | or modifying an SDR. Trying to use a common PC as | a "model" for an SDR is a bunch of nonsense. The | "bus" and "interface structure" is an analogue only | the broadest sense of the term. Doesn't apply, | either technically or organizationally. | | | |
