Did Europe's new standards for pc boards ground Airubs?

So, if an airline ordered a dozen planes, they would all be different? That sound more like a quality control problem to me.

Hello Michael,

Most likely they are serving the customers in a round-robin fashion. 1st A380 to airline #1, 2nd A380 to airline #2 and so on. Then one is going to be different from the next.

IMHO this boils down to the usual: Lack of proper systems engineering and thus lack of planning.

We took care of that by taking lots of digital photos of the first chassis for each contract, so all wire routing was the same for every unit that followed. We also recorded the intensity codes on LEDs and displays so later units would match. We were an engineer to order shop so we had basic models that were stuffed with modules to do the desired job. I laugh when i see our early equipment on Ebay. They have no idea how its configured, but its a model 1100! There were over thirty different chassis in that series, some Telemetry, and some commercial C-band equipment.

Also, the spectrum displays are not repairable if the CRT is bad. We were having the rectangular CRTs custom made, after the OEM dropped them from their regular line.

is one of the many 1100 series, but it is useless without the missing parts.

Hello Michael,

But that would be way too practical for a modern day operations ;-)

How did you take digital photos back in them days? We still used Polaroid in the late 80's.

That's de-facto the same with all used gear. CRTs are nearly always cost-prohibitive so the only way out is to buy another unit that has other problems and scavenge the CRT out of it. This is why most people own several Tektronix 7-series mainframes. If the CRT fades on one you move to the next.

Yellow buttons. Pretty loud for those times. Our marketeers would have never let us do that.

It was the '90s, and it was a Sony digital camera.

Those are indicators with built in lamp self test. If you suspect a lamp is bad you push on the lens to test it. they were color coded so you could spot a problem in racks full of equipment, from across the room. these were built for NASA and other government agencies that liked the layout, and reliability. When I left Microdyne in 2001, there was one of the first receiver they built still in daily use over 30 years later, and it had never been powered down. The company was started by a couple engineers and one salesman who left "Defense Electronics" to build a better telemetry receiver. A couple years later DE was out of business.

How do you like the RCB-2000 series styling? It was the last product I worked on:

Hello Michael,

Nice. But the site doesn't allow a close-up peek.

.Thank you one and all. But it seems as though most of us in the US are not quite aware of the potential problems in doing away with tin/lead solder connections. We are the only country in the civilized world using inch/pound and rightly so because we lead the world in technology because of it and other things such as democracy, great schools and capitalism. But if we are forced to go metric (to the benefit of our competitors who will no longer have to translate all our technical data and we do it for them for free) or into the idiotic idea that lead free solder will solve all our environmental problems as conceived by a bunch of gray haired French elitists.... enough!

I can't go on. It sickens me to see how stupidity reigns.

L3 is paranoid, but Microdyne had huge photos. The radios were running embedded NT on a 586 Cyrix processor when I left. The display is a TFT, and the row of menu buttons next to it change with the desired functions. It had a high speed RS-232 interface, high speed RS-422 interface, and IEEE-488 interface, and an Ethernet interface as standard equipment. there was an optional digital spectrum display, but the computer engineers screw up the design by trying to pour all the data through a 9600 baud RS-232 port, even though the PC-104 SBC had an unused high speed parallel port. They were still trying to fix it when I was laid off. 38400 baud would have been fast enough for a little over half the data required. They were going to compress it in the SD module, and uncompress it on the SBC, rather than fix the real problem. The engineer in charge of the section was a real jerk. His desk was covered with "South Park" toys and he acted like he was nine years old.

That base model radio was about $80,000 in 2001. It would have killed you, because they didn't have to pinch pennies at every turn. ;-)

Explain to me how being the only country in the world still using an obsolete system of measurement is an advantage.

This is the instrument the company had when I started (about 1980). We expanded to 48 input channels, 16 output channels, X-Y CRT, electrographic recorders, and GPIB data dump to PDP miniframes, most of it in a 6-foot 19" rack. The block hanging in the back in the rear view is a 5V power supply.

try reading some non US web sites, you may find that you have a somewhat blinkered view of your own importance

Hello Richard,

That's almost pretty enough to be next to the stereo in the living room. I like those aluminum knobs. Very posh, looks expensive.

Yes, I was surprised. I was talking about fly by wire and you said it was all done by hydraulics so I took a guess at what you thought you thought and I get to be the idiot because you are stupid.

In the meantime you snipped all that stuff you wrote about jodhpurs, warm dubbin and the mother of the girl next door.

I think I've seen one of those on a bench somewhere. Maybe at one of the surplus stores around Orlando where a lot of Lockheed-Martin scrap ends up.

PLONK!

Obsolete? We lead the world in innovation and technology you dumb ass!

66% of our gross national product is intellectual property from the design of machines, engines, software, movies, buildings, ships, airplanes and you name it. Other nations must copy and translate our inches and pounds before they do a damned thing. You want us to translate our own magic for others to copy? You really need to shove your head up your ass.

Wayne

So what? Non US websites simply promote their own ignorance. Show me a significant non-US innovation on the world today. Sony got their start from Shotkey's invention. Casio got their innovation from TI and the Swiss quartz. Or Microsoft, or the movable tailplane to make supersonic possible, or Coke. You are really demented.

Wayne

Can't. Yours is already up there and there really isn't room for it..

The three phase AC electrical system - Tesla (Smiljan, Lika Austria-Hungary). Edison's DC system was a dead end which could never have progressed.

Radio - Tesla. Copied by Marconi.

Induction motors - Tesla.

Fluorescent lights - Tesla.

Just for a start.
