    After Guan Fei did the same thing on the back, he handed the copper foil plate to Shu Cheng for inspection.  Although he moved quickly, the tape was very sticky and there would inevitably be a little residue, which required subsequent personnel to remove it with a very thin flat file.  He used this time to check the work progress of others.  Guan Fei came to the soldier who was cutting the particle board with a bow saw. He saw that he was cutting carefully and kept the saw edge outside the outline line. He nodded slightly.  Leave a little more leeway, it¡¯s just a matter of polishing it a little more in the later stage.  If the saw is broken, it will be much more troublesome to repair.  "Well done, better than I expected! The particles of the particle board are relatively coarse, so it is difficult to keep the saw edge flat, and there will always be some unevenness. After sawing, use a file to smooth it first, then mix in some gypsum, and apply it flat for a while.  After polishing it, it will be very smooth." He praised it and pointed out the next steps.  "Yes!" Hearing his praise, the soldier became more motivated.  Guan Fei took a look and saw that the particleboard was easy to cut. With five or six soldiers working together, the box cutting went very quickly.  Almost one-third of the three large parts, the left, right and rear panels, have been sawn. The top panel and the front and lower panels are about to be sawed.  The console was a little more troublesome. It was not big in size, but it still had to have holes cut out inside to leave holes for rockers and buttons. A soldier held up the cut wooden board and turned it upside down, as if he didn't know how to dig out the holes.  "First use an electric drill to make a hole in the center. If there is a gap, you can put the bow of the saw through it, and then cut from the inside out. When you get close to the circle, then just cut along the lines." He clicked on the side.  One sentence.  The soldier suddenly realized it, slapped his forehead, and laughed at himself: "Hey! I'm stupid! I just thought that this has no edges and corners, and the saw and bow can't cut it, and my brain is over the top." "Haha, it's okay, just do more.  Well, practice makes perfect." Guan Fei encouraged him and came to the soldier who was cutting angle steel with a saw blade.  In the frame of the arcade machine, the picture tube and operating table are relatively heavy, and the load-bearing capacity is still a bit poor with just a few screw holes, so an additional support frame is needed.  Especially for the console, players press the buttons for a long time and sometimes beat them hard when they get impatient. Without a strong bracket, it cannot withstand it.  Originally, it would have been best to weld this support frame, but now that we don¡¯t have welding equipment on hand, we have to temporarily drill holes and fix them with screws.  The disadvantage is that the screws are easy to loosen, and after today, they still have to be removed and welded again.  Guan Fei turned around and looked at his watch. It was only 7:13.  Judging from this progress, we can finish the main frame without staying up late.  With his precise drawings and a small workload, the frame part really didn't take much effort.  When he came back, Shucheng had already finished the copper foil plate.  "Put the board into the plastic basin. Put this side down first, then put a glass rod on this end, and put it down slowly, being careful not to splash your hands." Guan Fei pointed to Shu Cheng and put the copper foil board in  in corrosive solutions.  As soon as the copper foil plate was put in, a violent reaction occurred where the solution came into contact with the copper foil, and the basin kept bubbling, as if it was boiling.  Guan Fei stared at the basin and saw that the copper foil exposed to the corrosive solution was corroded into holes in just a short time.  At a speed visible to the naked eye, the copper foil disappears into the solution, exposing the resin substrate underneath.  The light signals received by the eyes were transmitted to the biological assistant brain, and any subtle changes in the copper foil plate were monitored by him. When he saw that the copper foil was completely corroded, he immediately used a small hook made of wire to hook the pre-drilled  hole and take out the copper foil board.  Shu Cheng had already ordered him to bring another basin of water. Guan Fei put the board in and quickly washed away the remaining potion on it with a brush.  Using potion to corrode copper circuits is an early practice. Chip manufacturing also learned this technology, using potion to corrode the unnecessary parts deposited on the silicon wafer base.  The advantages of this method are low cost and simple technology, but its shortcomings are also significant.  The potion not only corrodes downwards, but also spreads to the surrounding areas.  Although there is gel on the surface to protect important parts, after the potion corrodes, it will naturally corrode sideways along the bottom of the gel.  Printed boards are better, the circuits are relatively wide, and a little corrosion will not have much impact. But for the chip, the line width is very narrow, and a little more corrosion may destroy the integrity of the circuit.  In order to ensure that there was no potion residue, they changed the water twice before giving up.  The next step is the highlight, and Guan Fei doesn¡¯t dare to leave it to others.  It's not that he doesn't believe them, but time is tight. Only by doing it himself can he ensure that it will be completed without any mistakes in the process.  He took a wooden board, put the completed circuit board on it, and used nails to fix the four small wooden blocks and secure the circuit board.?Pinch tight.  Then replace the small hand-held electric drill with a 0.2 mm diameter drill bit, and drill into the center of the circle reserved as the component pin position.  ¡°Squeak, poof!¡±  When one hole was drilled through, he raised his hand, pulled back the drill bit slightly, and drilled to the next pin almost against the circuit board.  ¡°Squeak, poof!¡±  ¡°Squeak, poof!¡±  ¡­ ¡­ Xue Yangyuan and Shu Cheng stood aside, looking dumbfounded.  Guan Fei's hand drilled holes one by one mechanically. The depth of drilling and the height of lifting when withdrawing each time were so consistent.  Watching him punch holes, it doesn't look like a human being, but like a machine.  With thousands of pins, it took a little more than half an hour to drill all the holes.  The average time required for each hole is a few seconds!  Xue Yangyuan now believes that if Guan Fei said it would take him one night to complete the product, because he remembers every step and every detail of the product so clearly, and his hands are so steady, it is definitely not a lie to complete the product in one night!  Others may not be able to do it, but he certainly can!  "Shu Cheng, sand it with fine sandpaper and smooth out the sharp edges of the holes. Be gentle and don't damage it." Guan Fei turned off the power, put down the electric drill, and handed the end of his hand to Shu Cheng.  "Okay." Shu Cheng was also stunned. He paused for a moment and then quickly took the fine sandpaper, touched the sharp places with his fingers, and started to polish it gently.  Guan Fei went out for another round and gave some guidance on everyone's work. This can be regarded as time-sharing processing in disguise All the particleboard parts have been cut, and the soldiers are rushing forward to use them.  A file smoothed the edges, and a warrior was already mixing water and plaster.  Perspex panels have also been cut and edge treatments are also being done.  The supporting steel frame is faster and the connecting screws are almost complete.  Look at the time, it¡¯s only 7:59!  He turned back and saw that Shu Cheng was still busy attentively, so he poured the corrosive potion into a plastic bucket, screwed the lid on, attached a label, and carefully put it away in the corner.  It took another half an hour before the Shucheng side was completed.  He took it and looked at the polished circuit diagram with a golden luster. He gently brushed it with his hand, not touching any sharp and prickly parts. He smiled with satisfaction: "It's done very well!" Shu Cheng chuckled, no.  He stretched out his hand and touched the back of his head with amusement.  Although the printed circuit board was mainly made by the brigade commander, he also had his own contribution. Looking at the shiny printed circuit board, he felt a huge sense of accomplishment in his heart.  Making electrical appliances doesn¡¯t seem to be that difficult!  Guan Fei took the circuit board and returned to the warehouse. While he was free, he had moved the desk from the room and placed it on the wall next to the power socket as a workbench.  He first used a small spoon to mix turpentine and alcohol, poured it on the printed board, quickly scraped it around with a piece of wood, and applied a thin layer on the surface of the circuit board.  This is to apply flux to it, which will make it stronger during soldering and reduce the possibility of false soldering.  He put the circuit board that had just been fluxed aside and waited for it to solidify. Then he picked out the components to be soldered, except for the write-once memory, put them in a convenient place, and organized them.  Turning around, he did the same thing on the back, connected the soldering iron to the power supply, and waited for it to heat up.  Xue Yangyuan followed and watched quietly.  Shu Cheng had the consciousness of being a subordinate, and when he saw that nothing happened to him, he took the initiative to help other comrades. However, he was full of curiosity about Guan Fei, and even felt that his rhythmic and stretched movements were all in harmony.  kind of enjoyment.  Guan Fei calmed down, took a rest, took the soldering iron and soldering wire, twisted a resistor, and accurately inserted it into the pin pad hole at the marked position on the circuit.  Attach the soldering wire, press the soldering iron, and the pins are firmly welded to the circuit.  With no distractions, he repeated the movements of raising his head, lowering his head, soldering, raising his head again, lowering his head again, and soldering again, welding components one after another on the circuit board step by step.  As time goes by, there are more and more components on the circuit board, but there are fewer and fewer components to be soldered next to it.  Finally, the last component was soldered.  Wow!  A burst of warm applause woke him up from his mechanical movements. He blinked his eyes in confusion and looked over, only to see all the soldiers surrounding him and applauding him vigorously.  "Brigadier, you are so amazing! There are hundreds of components, and I haven't seen you miss a beat!" A soldier applauded and admired.  "That's right, my eyes are straight. I have never seen such a fast hand speed." Guan Fei put down the soldering iron and laughed and cursed: "You guys, why are you around me?"It's a circle and everything is done?  " "Brigadier, you don't even look at the time, it's almost ten o'clock!  We've already finished it!  "Bao Yaning took a small alarm clock and said with regret. "It's really almost ten o'clock. Unknowingly, I did it for nearly two hours in a row! Only then did Guan Fei feel sore all over his body, and his neck was as hard as a piece of wood.  The biological accessory brain can control muscles and tendons, but it cannot avoid the soreness and swelling caused by long-term fixed postures. For a while, he could not even stand up and could only rub his legs hard. "Brigadier.  , let me rub your shoulders.  "Bao Yaning leaned over flatteringly and rubbed his shoulders. "You flatterer!  Rubbing shoulders doesn't help either.  Guan Fei smiled and cursed, "If you go out later and I find you didn't do your job well, I will scold you all the same."  " "Hey, don't be afraid, as long as you watch it, you won't scold me!  "Bao Yaning said with a salivating smile. "Okay, then I want to take a look!  " Guan Fei stood up and walked outside the warehouse. Although he already knew something in his heart, he still lost his concentration when looking at the empty arcade frame. "It's really done!" He walked forward quickly and got closer to the machine.  Look. It¡¯s really done. Not only has the frame been fixed with screws, the assembly is complete, the rough edges have been smoothed with plaster, and even the handles and buttons have been installed. Even though it¡¯s the first time.  The workmanship is still rough, but the soldiers completed the tasks assigned to them excellently. ¡°Not bad!  Guan Fei looked at each detail and was full of praise, "It's done quite well."  I told you that particleboard cannot tolerate screws, and you remember it. Use expansion screws as the base and then tighten the screws. Well, well done!  " Hearing his heartfelt compliments, the soldiers all grinned and laughed happily. Guan Fei patted them on the shoulders one by one to show encouragement. Looking at their cheerful smiles, he was filled with emotion. They had not yet come into contact with the outside world.  They are relatively simple-minded and have not been contaminated by material things. They are happy enough to hear sincere praise from their superiors. Under their leadership, they will eventually see more, know more, and will be tempted in the future.  More. I wonder if they can still have this kind of simple happiness in a few years or more than ten years "Commander, if you make the circuit board, is everything done?"  "Zhou Xiaoyun also had a smile on his face and squeezed forward to ask. Guan Fei looked at his impatient expression and shook his head with a smile: "No, there are still things that haven't been done yet.  "    "what is that?  Let's help you do it together.  "Bao Yaning crouched, slipped through the gap, and volunteered. "You can't help at the moment. That's making a ROM, which is a program memory.  I want to solidify the program into a special integrated circuit.  It is like a script. The processor must perform corresponding data calculation and processing according to the script. When it is displayed on the picture tube, it is the picture we see.  "Guan Fei gave them a rough introduction in simple terms. "Can we do it tonight?  " Shu Cheng didn't know whether it was difficult or not, so he asked with concern. " He will leave tomorrow. If he can't finish it, he will have to leave with regrets. He hopes to see the product made and running today.  Let him go back and tell the political commissar and deputy brigade commander what they did in Hong Kong. ¡°No problem!  You guys take a rest for a while, I'll be fine soon!  " Guan Fei returned to the warehouse. The soldiers did not turn on the TV to watch, but gathered around him. Even if they could not help, they still wanted to accompany the brigade commander to complete the final work. Guan Fei nodded to them and stood next to the desk.  From the small cabinet, he took out a small cardboard box, opened it, and took out an instrument. "This is an EPROM reader and writer." Since everyone didn't leave, he arranged the blinds for them. "ROM is the abbreviation of the English word, which means.  is read-only memory.  The product we are making this time is an arcade machine, a large game console.  Usually, the arcade machines produced by various manufacturers have the game programs fixed in the read-only memory. The so-called curing is to make an integrated circuit with a fixed circuit. It is the same principle as today we only make printed circuits and welded components.  It's just that it's smaller, as small as a finger" Others didn't quite understand it yet. Shu Cheng, who had made printed circuits by himself today, immediately understood it. "It's just that he still didn't quite understand how it could be so big.  How high a level of technology is required to make a printed circuit so small and fit it into a device the size of a finger? " When we make a game console, we also need to solder a solidified game program.  ROM.  But there is no manufacturer to help us produce, what should we do???  "Guan Fei quickly installed the EPROM, performed a power-on test, checked whether the circuit was normal and whether there were faults, confirmed that everything was intact, and continued to explain, "Then we have to rely on things. ? ROM cannot be changed once it is produced.  However, its production cycle is long. To make a ROM, you need to make a special board for it, which is too expensive.  Sometimes people develop a program and want to test it, but it is impossible to use ROM.  In 1956, a Chinese scientist invented PROM, which translated into Chinese is programmable read-only memory.  " "Wow, we Chinese invented it!  "    "very impressive!  "The soldiers screamed in surprise, whispering to each other, and they were all proud of the Chinese people's intelligence. Xue Yangyuan's eyes also lit up when he heard this. He also knew only a little about electronics, and he had no in-depth knowledge at all.  You know, I couldn¡¯t help but be excited when I heard the news. ¡°Haha, Chinese, well, I can count myself Chinese.  "Guan Fei knows that in this era, the concepts of overseas Chinese and overseas Chinese are still relatively vague, and he does not understand that the Chinese are already foreigners who have joined other countries. Of course, there is no need for him to correct everyone's misconceptions, and it is also necessary to enhance his sense of pride.  Okay. ¡°PROM is a part of the data storage circuit connected with a special fuse that can be melted by electricity.  Because computers are represented by power-off and power-on, when entering a program, you only need to melt the fuses indicating power-off in sequence, and the program will be fixed in the memory.  "Maybe Xiao Shu understands this better. Just like the circuit board we make today, if we use a circuit board with densely punched holes, a welding wire is used to connect the holes.  When we need to make a circuit board, we only need to melt the excess solder wire to make a circuit board that meets our requirements.  "  There is a small LCD window next to it, which displays the program he entered. This kind of equipment is still very primitive and cannot make logical judgments, so you need to concentrate, input an instruction, and stare at the program line fed back by the LCD window.  Check to see if the input is wrong. This is relatively easy for Guan Fei, and there is no need to be distracted. The biological assistant brain will automatically detect the error and give a warning prompt. After Guan Fei inputs it, he will know that there is nothing wrong.  There is no need to check, just insert the purchased PROM and solidify the program. A piece of read-only memory containing the Space Invaders game program is released.
