If an average vacuum tube lasted 6 months, the whole thing broke down every 5 minutes. Prior to transistors this was the terror of engineers.

> If an average vacuum tube lasted 6 months
This is a common misunderstanding about reliability, whether talking about solid-state or tubes. In fact, any manufacturer worth his/her salt can predict, with surprisingly accuracy, the number of failures over time -- say, 1% in the first month, 10% by the end of the first year, and so on. How they do this is fascinating to those who are interested.
http://en.wikipedia.org/wiki/Quality_assurance
Thus, you can buy electronics, made in the same factory, by the same people, but one branded "Sharp" and the other with an off-brand name -- identical units -- but one has a 90-day warranty, while the other is 1 year. The latter will probably cost more because ('ere's the secret) the cost of the warranty is factored into the price of the unit. (Moral: a longer warranty does NOT necessarily mean a better-built device. Another secret that "They" won't tell you.) :)
In this case:
1. You test each tube thoroughly before it's even approved for use in the computer. (This testing is one reason why "mil-spec" components cost so much.)
2. Since each tube is about the same age when the computer is first built, there will be a *window* when you expect to begin having cascade failures. You schedule PM (i.e., tube replacement) to occur *before* that window. For each of those 60,000 tubes, there's a replacement log.
This is a great example of how statistics can mislead. When the first really big computers were proposed, there were indeed some who argued that they'd never work, because with 10,000's of tubes, they'd be constantly breaking down. But real-life proved them wrong, thankfully.

Macs, not just for product placement by antifoidulus · 2013-12-23 17:15 · Score: 1

The article mentions how macs are often used for product placement, though it doesn't seem to cite any sources showing that Apple actually paid for such product placement. Not saying that they don't, a source would have been nice. But anyway, Apple computers often appear in TV/movies/commercials when there clearly isn't any product placement, because the iconic glowing apple logo is edited out.

I cannot tell you how many times I have seen computers that were clearly macs have just a generic grey back because they weren't trying to focus on the PC. This is especially true in photo ads, but I have seen it on TV and movies as well. My guess is that the producers liked the design of the mac laptops, but didn't want to risk being sued by Apple or just didn't want their product associated with Apple etc.

It could also be that Apple's computers tend to be very distinctive and thus, easily recognizable. It's something that's a part of Apple's designs - they don't tend to fade and become just another generic widget in the background.
This is especially because Apple's made computers out of aluminum, which gives it a distinctive look all to itself. Having oddly-shaped PCs (think the iLamp and such) add to the distinctiveness.
Heck, Thinkpads were fairly common as well - given the red nipple pointer. Of course, PCs these days generally Dells which don't usually have many distinctive elements and thus end up blending into the background.

Actually, another reason is liability - a product placement often carries a pile of terms and conditions on how and when the product must be displayed, and how it must be shown. Some of these are understandable (e.g., a car sponsor may request that none of the cars used in live shots may be shown as causing intentional damage, or showing faults, etc). Usually, the items must be shown in a positive light and all that.
So not only do editors not want to give free ads away, they don't want to run afoul of any possible libel or slander by misrepresenting a product. By editing away any distinctive marks, they also can use it as a "generic" computer and not likely to damage brands or get sued.

Actually, if you consider iPhone vs. Android, that's true. But iPhone vs. other specific phone models, it's not so easy - the SGS4 and SGS3, possibly the two best selling Android phones, make up around 10% (combined) of the Android market, but both individually (including all the sub models) sold less than iPhones.
The iPhone is iconic, an Android phone is not - it's generally so bad that if there's a specific Android phone product placement, the phone itself will announce its make and model - e.g., Sony pictures phones will use Sony phones, but they often will have SONY plastered on them, and maybe even show "Xperia Z" or something when the actor uses it.
That's one of the big Android problems - sure they use s smartphone, but that's it. If it's an iPhone, it's obvious it's an iPhone. If it's a Windows Phone, ditto. But if it's an Android phone, that's practically any POS shape and size that's so generic it's fades away.
Hell, Microsoft Surface paid placements all have the actors snapping the keyboard to the tablet, and flipping out the stand. Otherwise it was likely to drown in the background of "windows tablets".
If you think form doesn't matter - it means the device is ignorable and is a poor candidate for product placement. Unless your item has a distinct design element (a la Apple, or Surface, or Sony) then the on-screen use will be very generic because there's nothing that sets it apart.

Reading those pages sure brought back a lot of fond memories of the day I got that big box from California ( I was living in Pascagoula, Mississippi at the time working at Chevron's big oil refinery there ).

I spent many an evening assembling and programming that thing - I had built my own keyboard and was using a couple of security type monochrome CRT monitors. I had two video cards in mine, each taking up 1K of RAM area, 30K of 2716, and the rest of its 64K address space was filled with 2102 static ram.

Me and the assembler had become great friends. So much so I had the assembler resident in a couple of the 2716, along with that famous little "Tiny Basic" 2K-byte wonder that showed up in "Dr. Dobb's computer journal".

The rest of the EEPROM space was mostly libraries I made that were callable from that little tiny basic, and they would do all the nitpicky bit banging.

I was especially proud of a hacked cassette tape recorder which I had modified to store data in a manchester format. I designed the hardware and file structures for it. Got my first experiences with phase-locked loops. CD4046. Basically it locked onto the carrier and looked for transitions between clock bits. I was feeding current directly into the write heads to do this, and adjusting the frequencies to use the inductance of the write head to limit the write current and leave me clean readable patterns on the tape. I learned a helluva lot about magnetics doing that. Filter design ( pulse shaping ) too.

I felt I could do nearly anything with that box.

I often wondered if I was the only individual in the entire State of Mississippi who had his very own computer.

It was my belief that I could run the entire refinery from that thing if Chevron would let me.

I feel very fortunate to have "come of age" when everything wasn't already done and I could enjoy building from scratch. Today, it seems everything is already there and off the shelf and all the enjoyment of rolling one's own is gone... now everyone "rides the bus" and goes where the bus takes them. I got to "walk the woods" off the beaten path, making my own trail. Sure, its oblivion now... but it was fun.

Note the movie trivia entry at this IMDB link: http://www.imdb.com/title/tt0064177/trivia

"When the executives at Control Data Corporation found out that Universal was planning a major movie featuring a computer, they saw their chance for some public exposure, and they agreed to supply, free of charge, $4.8 million worth of computer equipment and the technicians to oversee its use. Each piece of equipment carried the CDC name in a prominent location. Since they were using real computers - not just big boxes with a lot of flashing lights - the sound stage underwent extensive modifications: seven gas heaters and five specially-constructed dehumidifiers kept any dampness away from the computers, a climate control system maintained the air around the computers at an even temperature, and the equipment was covered up at all times except when actually on camera. Brink's guards were always present on the set, even at night. The studio technicians were not allowed to smoke or drink coffee anywhere near the computers."

When I started working at AAA's corporate office here in Washington they were still FedEx-ing boxes of 9-track tapes around the country to do data transfers in 1998. I made it a goal to get rid of the failing 9-track tape machine, and proceeded to contact vendors to arrange for alternative methods of data transfers. An awful lot of people at the other end of the phone had no idea what I was talking about. "Remember in the old science fiction movies, the big round tape reels that were on the computers? That's what we're sending you. Can we do this some other way?" That generally got me transferred to the right person.
By the time I left two years later we had managed to change everything over to direct modem transfers, encrypted email attachments, or a CD for the really large membership file that went to national headquarters. The last holdout was American Express, and if the tape machine hadn't finally given up the ghost we might not have changed them over at all. They just wanted us to send the text file to their FTP site. Unencrypted. Logging in as Anonymous with no password. Just dumped in a browsable folder labeled with our account number.

"it could transfer all the current from the low impedance side of the circuit to the high impedance side of the circuit"What does that even mean?? It does no such thing.

Because the first devices were junction transistors, early explanations were often around the common base configuration, in which this explanation is marginally appropriate.

Mass tube swapping ignores the "bathtub curve"... by Ellis+D.+Tripp · 2013-12-24 10:25 · Score: 1

This was a major lesson that was learned during the early tube computer era. The best approach was NOT simply swapping out tubes after so many hours "to prevent in-service failures", but periodically running diagnostics checking pulse levels, etc.to identify tubes that were actually starting to slump off.

The failure rate vs life curve for most components (tubes included) has a high initial failure rate (so-called "infant mortality"), followed by a long period of low failure rates, which eventually trends upward at an increasing rate at end-of life. This produces a curve with a flat bottom and 2 peaks at the ends, like a cross-section of a bathtub.

By swapping out tubes before they hit the end of life, you push the entire tube complement in the equipment over toward the "infant mortality" end of the curve, actually INCREASING the failure rate over careful monitoring and replacing only those tubes that are actually starting to fail. All that tube swapping also results in increased failures through the increased handling of the glass tubes (breakage and seal leaks), wear on the sockets from pulling and inserting tubes, etc. The highest equipment uptime was achieved by not actually replacing tubes on a fixed schedule, but by overall system checks to identify and replace individual failing tubes BEFORE they progressed to the point of total failure.

Experience with electronic installations containing tens of thousands of tubes produced a huge amount of statistical data on component reliability, laying the foundations for modern reliability models and MTBF calculations.

A good read from 1960, when all this was being figured out is "Getting the Most out of Vacuum Tubes" by Bud Tomer, available on Archive.org:

I'll see your 6900, and raise you a 7AK7... by Ellis+D.+Tripp · 2013-12-24 10:41 · Score: 1

, which was arguably the very first electronic component specifically designed for use in computers. Most of the magic was in the ultra high purity nickel used in the cathode sleeve, to prevent interface formation and "sleeping sickness", which would result from even the slightest trace of silicon impurity in the nickel.

Every electronics geek needs one of these on their desk. Fortunately, there were millions made, and they come up on eBay cheap, as they have no value to the audiophools....

I wonder what all those displays in the old TV series "Time Tunnel" were. I recognized the lissajous displays on their consoles... I was making the same kind of display when I was in high school trying to make a decent oscilloscope out of a TV.

I ended up making a Science Fair EKG project with it.

Incidentally, those lissajous patterns is damn near all I ever was able to get from that TV - it made a lousy - and I mean lousy - 'scope. It barely had the bandwidth to display an EKG, and even then you had to use your imagination as the screen phosphor persistence for that application was way too short.
