Even #1 all time sales items can be more valuabel than a lot rarer and more interesting speciemen of the same time - just think about the VW (Beatle), a car built in more units than almost any other car in the world, build over a timeline longer than most oter car (especialy longer than all other mass market car) but he outclasses all compareable cars when it comes to the $$$ peaople are ready to pay to get one. A bit like the APPLE II - maybe in 10 years they will be like a Kaefer. Or take the Altair a computer clearly never realy too be considered rare but the prices just outrun any other old computer (only the Apple 1 will perform higher, but it is also a lot more rare). > Yes the iMac will be collectable because it is taking a lot of new people into > the land of computerdom.

No new idea at all. Wasn't the Mac itself the same thing ? And unpack'n'go is not new at all. Even in the x86-PC world a lot of ready to use machines are available.

487 and Marketing Breakthroughs (was Re: 486DX/SX (was:

by Marty＠itgonline.com

When customers used to ask me to explain the difference between a SX and DX processor, I'd give the standard spiel (386SX is basically a souped up 286 with same data path using 32 bit addressing, 486SX is a coprocessor neutered DX) then tell them the easy way to remember is that DX stands for DELUXE, SX stands for SUCKS. Well, it works for me.....

No. The 487 is a *fully* functional 486DX, and it has to be, because when you plug it into a 487 socket it disables your 486SX completely and takes over. The 487 is NOT a "math coprocessor". It's a "Marketing Breakthrough" (*), or so they had hoped. The made the pinouts of the 486 and 487 slightly different, so that you couldn't take out your old 486SX and simply install the 487 in its place, which would leave you with a spare 486SX to give to a friend, i.e., less sales of new chips for Intel. Part of the reason it didn't work out in practice is that 486DX chips were generally available for less money than the expensive retail-box 487. Cheers, Eric (*) If you're not familiar with the concept of a Marketing Breakthrough, see this advertisement which appeared in newspapers nationally a few years ago: http://www.milk.com/wall-o-shame/dish.html Note that every statement in the advertisement is literally true; they even utilize italics to emphasize the fact that the product is nothing special. I didn't buy their antenna, but I offered to pay them up to $20 for a large poster of the advertisement.

Below are several messages from earlier in 1998 about this topic, and a related technology. Anyone want to make a jillion dollars? Re-typing URLs is a pain. OCR is a pain and impractical for small bits of text. Reciting addresses is a pain. I think we need a pen- or credit-card-sized device that can read barcodes. While I'm reading a magazine, I see a URL I want to visit later. I scan the barcode. Later, I transmit my pen's contents to my PC, maybe via IrDA. It's scalable from give-away keychains to smarter devices, it's embeddable. Make a PostScript font with the barcode. Allow one-to- one ASCII-to-barcode, upsell software to checksum it or auto-inject barcode text in any app's documents. Make a modem-like variation that can emit a few hundred bytes of info while held to the mouthpiece of a phone, as well as receive a few hundred bytes when held to the earpiece.

The data was recorded with error detection and correction information (Reed-Soloman, I believe), as well as redundant groups, so it could withstand misprints, marks, holes, and other flaws. This was all pre-CD, and the cost was very cheap. One of the names for them was TDB's for Transportable Databases. They were intended for software distribution, database updates, games on the back of cereal boxes, etc. Each track was a portion of a circle (about 1/10 of the circumference). The reader had a large (approx. 14") spinning wheel, and supported variable track pitch and data bits per inch (so different quality paper and printing processes could be supported), and could track media that was not cut square by skewing the tray that held the media (since there was no physical or optical "center" on the media -- it had a virtual movable "hole" to spin on). It used a Z80 microprocessor (running extremely tweaked assembly language by Al Jewer) and interfaced to a computer via "high-speed" RS-232 (9600 bps). I did demo software on a variety of hosts, including the Storm operating system (multi-user CP/M OS by Ron Fowler, also the author of the popular MEX communications software), Commodore 64, and IBM-PC XT. We had a Coleco Adam computer that we briefly considered writing something for, but it never stayed running long enough to evaluate. We did a multi-month trial of a large database update for a large company based in Moline. We sent out three months of updates to a 13M database. Each update was a half-dozen or so cards that could be scanned in any order and then the update was applied to the database. This was run at three dealerships that could retrieve up-to-date database information much faster than their microfiche system which was always out-of-date. It also displayed additional textual information that was on other microfiche or books and not usually referenced. This was circa 1985, and was quite impressive to the people who used it. So much so that the actual media technology took a back seat to the database system itself (an interesting lesson to be learned there). Newslog / Lab1 ran out of money before the technology could be completely finished and sold or marketed. Not that they didn't try. I learned a lot about "demos" and "demospeak" while I worked there. I still have some media around, but alas no reader. I'm willing to bet it could be read by a modern high-res scanner. An energetic soul could probably even write a reader emulator that fed the bits that it peeled radially from the high-res scan into the actual Z80 reader code to decode it. The best anecdote I recall regarding the technology was in the "camera" software that generated the film original used for duplication: the base unit of measurement was derived from the bits-per-track and camera wheel speed and other factors I've forgotten. All of the internal calculations were based on this "tick", which varied in actual length, but was approximately 1mS. The camera system's author was Bill Whitford, and the unit of measurement henceforth became known as a "willisecond." Bill's code ran on a much larger processor with a lot of memory (I think it might have been a 4Mhz Z80 with 64K of memory), so he development in C.

Collectable PCs

by Marty＠itgonline.com

Does your Columbia list it as having been made in Columbia, Maryland? I believe their early pc's were made in Columbia, Maryland, later they moved to Florida. Marty ______________________________ Reply Separator _________________________________ Subject: Collectable PCs Author: classiccmp(a)u.washington.edu at internet Date: 11/8/98 5:58 PM Earlier there was a discussion of what PC stuff might be collectable and valuable. The other day I ran across an original Columbia PC. This one is a good collectable. It was as it came from the factory with the original Floppy and Hard drive. It also had the original keyboard with it. It was very clean and had not been abused. It worked. In my 1983 Bytes they were asking $5000 for it. I paid $6 at goodwill with the intention of putting it on ebay just to see what it will bring. I am retireing from collecting but if I were going top sit on a piece of equipment this would be a good example. My reasons in order of priority: 1) first popular clone, 2) all the original -parts (including screws), 3) Clean with no scratches, the type on the keyboard showed no wear, 4) Works (not essential - i bought it without testing it - $6 is not a great gamble), 5) Rareity - Most of these go directly to scrap and have for years. However it will be many more years before it is truly valuable, but I bet it will be!

It could be grounded or it could be floating. But as long as the connector supplies power and the return path (two wires supplying + and -), you should be able too leave it disconnected from ground with no problem. Circuits are grounded for two reasons; (1) to provide a power return path through the chassis and saving the cost of a wire or (2) for safety reasons. Reason 1 is a poor practice since chassis grounds aren't very reliable and cause galvanic corrosion. Reason 2 is generally only required in high voltage (> 100 Volts) crcuits. Joe

A friend at a placed I used to work showed me a postscript file he had downloaded from somewhere for printing your own optical mouse mats for a Sun (his had a bad scratch accross it). As a temporary stopgap it _might_ work (need a colour printer though!). Dunno where he downloaded from though, but contact your friendly neighbourhood seaqrch engine!
