Chapter 50 Vacuum Tubes

The cable car goes deep into the tunnel along the cableway, and the dim light above the head shines on both sides of the dome to form curved arcs. Looking forward, it seems to be in the body of a giant snake, and the light arcs are the ribs of the snake.

151 is a huge underground ant nest. Even the staff inside the base seldom go through all the tunnels in the entire base. Its main structure looks like a huge H from top to bottom. The difference of this H-shaped tunnel is Some belong to different departments of the base. Temple 104 is in the main cave on the left and is responsible for the maintenance of Red Lotus, while the main cave 105 is on the right and is responsible for other tasks. The personnel in the two main caves do not communicate during working hours.

151 is such a place, if you don't carry a map with you, you don't know where the deep tunnels you see lead to.

They may take you to an unexpected destination, especially in the dead of night when no one is coming and going. It is entirely possible to turn around 151 for hours and find no way out until the next morning you hit the bus to work. Comrade, so the workers and cadres in the base have always only followed the road they are familiar with.

Old man Ji led a group of cadres from the equipment department and logistics department in the cable car. They got off at the platform of the 105 main cave, and rushed to the 112 workshop.

There are a total of three maintenance workshops for giant machinery in the base, 110 is the special workshop for Honglian, which is the most important one, 111 is the spare workshop, which is currently empty, and 112 is the coolest one.

Because here is the coolest giant machine in the world.

The code name is mock wind.

It is the only all-vacuum tube computing core steam power technology verification machine in human society.

This is a project that old man Ji personally led the technical team to tackle key problems. No one can tell that this bad old man with a bad face on his hips and a heart of Warhammer 40K can come up with such a punk thing. The original intention of the design was derived from people's concerns about the super electromagnetic pulse - the 001 Seraph not only almost overturned the North American continent when it erupted, but also caused the most powerful and longest electromagnetic pulse that humans have seen so far. It reimbursed half of the world's Electronic products and all satellites, the high-energy charged particles in the upper atmosphere do not dissipate for several years, and even affect the earth's magnetic field in turn.

This lunatic angel made the weapons in human hands useless overnight.

EMP is the natural enemy of any sophisticated electronic instrument, especially giant machinery. Its combat relies on the powerful computing power of the computing core's trillions of floating-point operations per second, but the more sophisticated the integrated circuit, the more afraid of electromagnetic pulses, unless You use a huge Faraday cage to completely wrap the entire giant machine and isolate it from the outside world, otherwise the surge current caused by the EMP can burn the giant machine to scrap iron in a few seconds.

Imagine this situation: the second angel with the ability to cause a super electromagnetic pulse burst (Ji old man believes that there must be such an angel), it can instantly put the human communication system, command system, and decision-making organization into a long-term Paralyzed, human beings' modern civilization based on Maxwell's equations has nothing to do with this kind of attack that hits the weakness directly, and it can make the giant machine go offline at a distance of [-] kilometers.

Old man Ji still remembers the disaster in the big collapse.

So he presided over a strange and even weird project (if it weren't for the old man Ji's seniority and status, such a nonsense project would have been difficult to pass the approval), when everyone was busy upgrading the system, making the computing core more and more sophisticated , in the general trend of faster and faster calculations, go against the trend, go upstream, find another way to dig out a long-decayed antique from human history.

This old antique is as old as old man Ji's father.

- Vacuum tube computers.

What a Luoyang shovel, the grave was dug so much that even Captain Jin would give it a thumbs up and call it professional.

If you want to use four words to describe the vacuum tube computer, it is: silly, big, black, and thick.

The calculation speed of dozens of tons of gadgets can’t keep up with the “return to return to return to zero” calculator. If it wasn’t for the super EMP that could burn the calculator together, it would be better to put a calculator on it with this thing, but it has an irreplaceable The benefits of this - not afraid of lightning strikes, not afraid of gamma rays, not afraid of electromagnetic pulses.

It's simple enough, what is a vacuum tube?Three metal electrodes are inserted into a sealed glass bulb, the inside is evacuated, and has the function of one-way conduction. It is such a simple thing. The big wrist is thick, and the small finger is big. The vacuum tube of the 21st century is used in daily use. Almost extinct, only some high-end audio equipment will use the vacuum tube as a gut, pursuing a "treble, sweet, mid-range, accurate and deep bass, in a word, it is transparent".

A vacuum tube can represent a 0/1. A vacuum tube computer strings thousands of glass bulbs on the board to form a logic circuit. It is conceivable that its size, weight and power consumption are hard to predict by modern people. With the microelectronics technology of the 21st century, a cumbersome computer that occupies an area of ​​more than an entire manor can be reduced to a huge scale integrated circuit, which is only the size of the fingernail of a little finger.

But with a wave of his hand, old man Ji set the clock back to the 40s. The technical level of the vacuum tube computer is not much different from the ENIAC, the first computer in human history. The bomber built in Bletchley Manor was so advanced, old man Ji resolutely carried this old antique onto the battlefield, just like the era of starship confrontation. The general puts the guns out—was it behind?Being behind, but the shells can ignore the opponent's guidance interference and bombard the mother, so being behind is not a shortcoming!
Too fucking Warhammer 40k.

If one day the angels burst out again to participate in the super electromagnetic pulse sweeping the world, and all the giant machines of human beings are scrapped, then Xiaofeng will lead a large group of vacuum tube punk steam-powered hydraulic giant machines to the battlefield, think about it!What kind of scene was that? Colossus soldiers covered in steam walked on the ground, their brains were vacuum tubes glowing with light and heat, the driver sat in the cockpit, with steel cables on his hands and feet, and the risk of death in front of his eyes CRT monitors and mechanical instruments with green light, bangs and a strong smell of engine oil everywhere——

It's really wonderful, but it's a pity that I think too far... Old man Ji shook his head.

He put his hands in his pockets and stood on the work surface.

The huge machine hangs in the cave, with only half of its body. Unlike Red Lotus, this huge machine is pitch black, with thick pipes and cables hanging down from the fracture in the waist and abdomen, like the internal organs of a giant.

It was covered with a huge plastic sheet, and the workers in workshop 112 were pulling steel cables to lift the plastic sheet.

Old man Ji slapped his hands vigorously in the empty cavern and said loudly:
"Let's try one hand first! Little ones! Fire up the boiler!"
