so now we're in front of the IBM stretch model 70 30 which is a supercomputer technically this was the fastest computer in the world in 1961 they only built nine of them in 1961 so that's you were working on this right that's right as some kind of fetal thing there was the crate what about the crazy for computer is that before this right after that was from the 1976 ok so there's great the Cray one yeah sacré one was after this and what's is there anything special about this time we need to know this was one of its massive is one of the pretty much the first big computer that had transistors and before that everything was vacuum to write it had one Meg of memory it costs eight million dollars is that one megabyte of ram one megabyte of RAM do you know what Ram type it was it was core memory core memory yeah what did core memory look like it was basically is that like all the wire doughnuts ok I was iron donuts with wires through and then the the Cray that came after it did pray sort of put this out of commission I guess that's how do they replace this or no there was a whole bunch of pastor supercomputers in between a Cray worked for cdc ave a via an IBM sort of lost the supercomputing business at some point sort of like they lost everything now yeah except for Watson except for what that's apparently the future yeah I like the panel if you like if this was your PC you could see what in this insight every one of your registers because it displayed at all is that what that is yeah these are these are the registers where the program counter is so you could actually see the machine running and where were they I guess if it halted you could tell exactly what was inside of a time time for for folks who don't necessarily understand that any type of programming when we're looking at registers I mean what is it actually telling us like when you look at this stuff the belly goes with her in them yeah then what's over here is that more the same I think I took some pictures of this week the register one register to program count register word count register tape drives down here tape drive buttons anyway these are controlled that's just some big control panel and control panel wouldn't make him Henry 48 million dollars I don't know if that eight million dollars is the is nineteen sixty one dollars or modding down romanik if it's modern dollars if it's 1961 dollars it's like 50 million dollars are circling how much room for eight megabytes or one megabyte by eight million billion dollars for one megabyte yeah a machine with one megabyte of ram does this have a speed anywhere what was how fast is this 714 thousand ads per second what's our ads as in like had two numbers together yeah so why did they measure it that way let's let less than a megahertz well good megahertz you double but one millionaires per second okay so this thing was pretty slow why is it measured in ads per second why specifically that's just that's just what they decided that's just what they decided let's talk about the so let's talk about the Cray one for a minute so cray Juan made by Cray research of course what do you know about that one I actually worked on the Craig 1s moves a basically a Fortran machine and it's sort of like a modern processor in a way because you don't want modern Intel you have a bx the head vectors just like that on this machine so you could add 64 so you can think of a px when you worked on it what did you do on it I did the electromagnetic field calculations for actually designing what was the pre XMP right the more modern ones so we were modeling the twisted pair that hooks together the circuit boards now you would have traces on a circuit board hooking the memory to the CPU back then they did it with twisted pairs and physical wise physical wires this the Cray one was I think was running at 70 megahertz which was the fastest machine in the world time so seven is my guess is all single core I this is back before the one that came after the supriya X and P at four course all right okay so they actually build a foreign an eight-core version based on this one right into the 80s I saw want it so this is a c-shape the Cray one the reason is a c-shape is they had a timing problem right she wanted to keep the maximum distance I believe between circuit boards wiring it was eight inches so in order to keep the timing they made into C shape the power supplies all through the bottom of it so it power like a locomotive right it was it was and it was not cheap i think that that thing was like 10 million dollars wellin tall leather it's all leather yeah it's all leather what is the case okay it's encased in leather no and get the leather in any color you're right one of the other things there's like a liquid-cooled that's a Cree too so just over there yeah the crate is liquid cool that was liquid cooled with fluorine okay and each create two came with a custom waterfall for the millions of those you got a custom water is a waterfall functional or was it just feels like it was just for looks okay so it made it look cool right but the liquid I guess felda there's what kind of like what was it chlorine fluorine some kind of worried falls down and just pumps through what did it cool a CPU or something or cooled the whole thing the entire machine was immersed in it okay and it would pump it through and take it out running through the waterfall and chill it and it would come back in so they were pretty neat to look at so that's on the earlier supercomputers I guess yeah with liquid cooling and then just days ago we saw Nvidia's two-hundred-thousand-dollar wasn't even a supercomputer it's just a high-end box for whatever that was 126,000 yeah yeah it was 170 teraflops yeah and my clothes these away there are millions of dollars what do you get rid of a crate I don't know I guess to be fair modern five-hundred-dollar computers probably better than these right yeah quote away yeah so one of the first things roller can i hear is the ram ack which is the first destroy disk drive and it's got these massive platters i don't how many of you flatters run there's a 50 pod rooms its steep platters and that stores how much data five megabytes five megabytes so something like five million characters five megabytes of data and you've got 128 megabytes so this is a micro SD card that we shoot with you can't even see it on the camera I'm sure 128 gigabytes right but twenty thousand times more on this then and this is a lot more faster what's the ram I ex Ben's at a 1200 RPM 500 rpm 1200 RPM it stores 5 megabytes of data and it was on lease right was on least thirty thousand dollars a month converted if you got a small computer with it from IBM and when was when was it made 1950 cilic ison so 1956 that is the first disk drive and we've got plenty of beer all of it but there's some other cool stuff too like we're talking earlier about some of the early storage on tapes obviously tapes predated this is that right tapes predated this and then drums also predated right we have some b roll of drums yes yeah so that's the ram ack and i guess in our day we're going to see the end of the disks are in the next few years so yeah this is the beginning and we're gonna see the end
