That’s honestly such a cool thing to do. Goes to show most tech savvy people are gamers!

The Amiga A500 had Rock Lobster/B52s etched onto the motherboard.

It’s a pity the modern corporate chip fabs are cracking down on them so hard. 😢

this first adoption of this chip was in pay phones.

That is impressive.

@@dtiydr how ?

I can break down every fuction block on the chip I have the og design files. My grandfather worked for Rockwell well into his 60's he did asic design layout work he is the one that put the coin slot in the design 😉

@@ZoeyR86 That is so awesome! :D

30 years later they still manufacture them the same way… Literally.

@@dingdongdaddy589 except the transistors went from micrometers to just a few nanometers

I remember seeing the original '4040' ic chip in the late 70's. By today's standards..it belong to 'the flintstones'. Back then..it looked like something from Star Trek!

The only time you get a wafer like that is when something goes horribly wrong and all of the chips are bad.. otherwise the square chips are sliced into the rectangular sections you see and mounted in a package, tested and sold for further integration into circuit boards in products.

​@@dingdongdaddy589similarly, but not the same. photo lithography has come a long way in 30 years

​@@wickedcabinboy Trumps? Have you seen the current president?

Not decades, would be a year or two to build another factory. Builders and such generally like to exaggerate lead times and costs

It took seven years to rebuild one fab that burned in Taiwan..

If we REALLY need it, many balls would be busted to get at least a new "first" fab built to start producing again. Why have we seen no aliens? Because we are the aliens.

If all the fabs blew up, it probably *would* be a long time before calculators started getting made again, but that's mostly since there are already so many calculators that have been made and people who need them could get them second hand. With such a sudden chip shortage, any production capacity would be used for things much more important than calculators.

This needs to be highlighted! I believe you are right! (I‘m working on investing in a wafer prober for my IC design house company atm)

What's a probe station?

@@joshyjosh8817 Such as an Electroglas-4090. Wafers don't contain all working dies/tubs. So you will typically use a probe station with a specialized card that has very small (almost microscopic needles) that will probe each die (and then a system connected to the probe card can perform tests on the die and mark them as either good or bad). A wafer like the one shown might actually only contain 60% good dies. After the wafer has been probed, a wafer map is sent along with the wafer when it is to be diced, packaged and wire bonded.

​@@D.E._Sarcarean i can relate to this. i knew some machine that are use at probing die like electrictroglass 2001x,4060,4090. I'm actually amazed by how the Platten works. 😅

Came to comments looking for this

Men of culture

I could tell immediately by the baseplate of prefamulated amulite.

1992 must have been the best job in the world

@@gfixler right it’s crazy they could prevent side fumbling on such a small scale

@lalec2000 pretty awesome, someone in another comment seems to have identified it perfectly and says it was used in pay phones and modems

That's not a flaw... it's actually in the Hayes command set. ATH0 is exactly how you end a call.

@@williamsteele It was a flaw because it could be used by anybody to disconnect the modem. Please notice that I didn't call it a bug or a hack

@@mattd1188 So, the Hayes command set specifically supports that mode. I think what you're referring to wasn't anything to do with the +++ATH0 string, but rather how it was implemented by other companies. The +++ was where the issue was... in that normally, Hayes modems would normally wait for 1 second before allowing commands to be sent. Non Hayes modems didn't wait, so as soon as they saw the string, they'd hang up if it followed by ATH0... which is actually two more commands... AT (Attention) and (H) Hook with a 1 or 0 being the Off-Hook or On-Hook parameter. Now, with that said, ANY command can be issued, for example, +++ATDT12345 would also execute immediately, which would dial 12345. That would also cause an issue. But this never really played out in the real world because of the software and protocols in place to prevent it. And, this issue still presented itself in real Hayes modems as well... it was just that it was broken up and more hidden. For example, if someone issued a +++ (switch mode to Command Mode) and then issued a ATH0 a second layer, it would still hang up on the Hayes system. Later, Hayes and other modem vendors added the ability to hide that using initialization strings to remap those commands. Also, software vendors added filters to stop it. The issue wasn't really an issue with PPP or Hayes... it was a discovery in how modems started to be used for a new type of communications, chat sessions. On a normal PPP call, there are only two parties, but in Chat, there were many connecting to a single site... and if one bad actor injected the commands, a lot of modems would see it and hang up, kicking them out of the chat. Once discovered, we put filters in place that would prevent that from being transmitted and instead would hang up on the issuer instead. Problem solved... but still not a flaw or bug in the Hayes command set. It was just found that when used in a scenario that Hayes had never thought of, it could be used maliciously. I'd liken it to someone driving a car into a crowd... there is no flaw in the car, it's just the driver using it for something it wasn't intended for.

@@williamsteeleRight, but it's not supposed to respond to ATH0 from the *other side* of the connection.

@@AureliusR ​ The modem wasn't responding to a remote command...it was responding to a local command. If you looked at how that was triggered, it was a PING command followed by the hangup string. PING forced a remote computer (via the IIRC client) to respond with echoing back the command string that followed. So, the remote computer would locally respond to the PING by sending out the +++ATH0. Again, both commands are perfectly valid...it's that the operator was using the two tools in a way in which wasn't designed for or anticipated. PING isn't a modem command, but rather the chat client that was doing the dirty work. Again, nothing wrong with the modem or the commands themselves... the combination of IIRC's PING command functionality, coupled with the +++ATH0 command is what would cause the issue.

we still bang rocks together, why do you think the yield is not 100%

It's for a payphone

That's a dam good guess 😂

Just because there is a cartoon bird on a board doesn't mean anything. It's art, many many boards are decorated with this artform. Those who know, know.

Not likely. Rockwell are not known for communication systems.

​@johnnygoodman2003 it literally is. The first adoption for this chip was payphones. Want proof? Go to the top comment. Google it.

If you look carefully, you can se my house.

My favourite is a millhouse from Simpsons hidden in a chip mask

I think everyone understands that. It's the use of the chip that is unknown.

pics?

Not a little joke. If somebody copies the chip that microscopic writing can be used as proof that it was a copy.

Circuit City if you will

Yup thin film interference and diffraction

Thin film interference but not diffraction.

​@@deang5622how is a bunch of parallel lines of one material on another any different than a diffraction grating? Only difference is air versus a different material. This is a basic electrostatics boundary / index of refraction problem.

@@onradioactivewaves The three optical phenomena are: diffraction, refraction and reflection. Thin film interference comprises refraction and reflection, *NOT* diffraction. This debate is over. Go research the phenomena and keep on researching them until you accurately understand what they are.

@@deang5622 theres no debate. I studied electrostatics and electrodynamics. I didn't say anything about the thin film phenomenon, I said the traces can act like a diffraction grating, difference being a material other than air. I didn't even mention "thin" as to no confuse it with the thin film phenomenon, but it would indeed need to be thin enough for the light to pass through and have some of it reflect back through the parallel traces and scatter around the edge, same as it does in a diffraction grating. Theres more than 3 optical phenomena, what about chromatic aberration just to name one. Diffaction occurs around edges due to what's known as a boundary problem in layman's terms and what happens to a plane wave going though one medium to another around a surface. Go brush up on Maxwell's equations and the "integral theorem of Helmholtz and Kirchhoff" or the "Fresnel-Kirchhoff diffraction formula" and then you can argue with that establiahed science if you want to have your debate.

Hence why chip designers refer to the area used for a feature as "real estate" !

I tried to picture clusters of information as they moved through the computer. What did they look like? Ships, motorcycles? Were the circuits like freeways?

Search "forbidden city" guys..

Both are human-made machines, just with different scales and purposes.

Seen the original lately? I think you might be confusing “Tron” with another movie.

This was the controller for a payphone, likely that was the reference for, and not tron.

@@StarsManny Bring your keyboard sword somewhere else

Well, we're comfortably in the hundreds to tens of atoms range these days. well beyond the wavelength of visible light, the only way to image the circuits is with electron and atomic force microscopes. Its to the point were we have to take into account random tunneling of electrons due to quantum fluctuations.....we're literally building things atom by atom and hoping the charges stay where they're supposed to.....

Question: does that thing that google images does where it loads a low res image first and you dont know a high res one is coming, so when it snaps to the high res ones it feels like your corneas have been slapped happen to you too?

Just make sure you're using the updated version. The flaw in the drawn reciprocating dingle arms interaction with the hydrocoptic marzel-vanes as revealed in 'The City of Detroit v. 17 ball bearings, more or less. 1963' can lead to fluidic decoupling in the hyperboloid wang shaft supports, which of course pegs out the graham meters, leading to a rapid distribution of the amulite casing. ......A woman lost her child...... Luckily the production and successful use of Milford Trunnions was unaffected thanks to their use case being tolerant of the deplaneration and side fumbling resonance. You know, because of the prime periodic curve function regression. But, I dont need to tell another engineer about that first year uni stuff.... Steve Lehto has a video on the matter I highly suggest.

@TankR It's so refreshing to hear from another true engineer and of course I am aware of that fateful day. A real humbling moment for engineers everywhere. A reality check on being sloppy with ball bearings.

Dude, MEMS technology is a manufacturing revolution that doesnt get nearly enough recognition..... Like, yeah, packing transistors in is indeed freaking amazing. But, IMHO, the last big thing in the hardware space has been MEMS. I wish it was a bigger deal to people....

Don't be. This is nothing compared to modern lithography. 1992 was probably around 200nm, where as a lot of modern cpus are 7-14nm and the latest ones like apple m3 chip are at 3nm. Were at the point where were contending with atomic tolerances.

@@sonacphotosjust because modern technology is even crazier, it doesn’t mean this isn’t still mind blowing
