  1. Well, for one. This is not still ongoing, sadly. Basically, I started working on having multiple sequences of ROM, so that it could utilize logic and loops, but I kinda lost the will halfway through. After a while, I updated to new versions of minecraft, and red-power didn't... I (probably) still have the world, but I don't even remember the modpack I made it with, and I don't have much desire to continue with it. As for the arithmetic, it was basically a ton of searching on Google images for logic schematics. Some parts (like the multiplier and the subtraction system) I had to just come up with myself. (btw, in these pictures the subtraction system is not properly done; I honestly don't remember what was wrong, but don't copy it exactly if you're gonna use it.) As for that display, it is very impressive. Modulated signals are beyond my level of work. Very cool. PS. If I sound somewhat uninformed, here's why: I don't have a clue how computers work. I made this up as I went along. I just kinda came up with this design myself, without knowing how computers really work. I knew some things, like the clock and the RAM, the ROM, and basic binary logic, but the way you can turn that into a functioning computer was beyond me. As such, many of my systems might seem unorthodox or inefficient to you because they're just some system I came up with off the top of my head. EDIT: PPS: I actually started to make this computer in real life, using electromechanical relays... never finished, but it was still fun.
  2. Mine was working just a few minutes ago, but now I can't load any of them... idk what the deal is... EDIT: well... about 10 seconds after posting this, it decides to work. Maybe the servers were just overloaded. hmph
  3. I've noticed a pattern... Vanilla has been aquireing several new features that don't seem to be entirely their own ideas. Let's see... Arrows sticking out of people~Pincushion mod 3D items ~ 3D items mod Fireworks ~ Fireworks mod Horses/Donkeys/Horse Armor/etc ~ Mo'Creatures Hoppers ~ Better Than Wolves TNT carts ~ Railcraft Really, the only original thing they have made in a while has been their comparators and the redstone blocks. At this rate, mods are going to go extinct! O_O
  4. This WAS happening to all my packs, but it magically solved itself for all but the plus pack, which still has issues... I have no experience, but I don't think its the plus-pack's fault, because it was previously happening with all packs...
  5. lol "byte" is just for conveinence. The Number of bits is determined by just how large any practical uses are. I don't need a 8-bit program counter becasue I i'll never have 255 commands strung together. As for square roots, I have a bit of code for that. I learned it from using an abacus (You know, those ancient things with the beads that slide on the rods, yeah, I kno how to use those to calculate square roots). The code only works for perfect squares like 4, 9, 16, 25, 36, etc. But is fairly efficient for the computer's use. It does involve division, Which is what i'm working to build as we speak type. Square Roots will be a series of commands, though, not a single command. Also, I just now realized what you comment on doing the math for wire lengths was about (the statistic of 17,506 meters of wireing). I did use WorldEdit to get that number, but I didn't use it for anything else, lol. That number is actually a bit smaller than it really is, because if you put a wire on the floor, then up onto a wall, it counts that corner as just one wire, when its actually two. EDIT: By my calculations, a kilobyte of RAM would be 384,000 Cubic Blocks. This means a cube shape about 73 blocks long, 73 blocks tall, and 73 blocks deep. O_O
  6. Yes, I have. I didn't use it because it is a bit of a pain to perform math with, unless you constantly convert back and forth, which is even more of a pain. I was originally thinking of a display much like that, but I later decided that the systems and memory needed to work with that are overly complex. Keep in mind, the computer (at this stage) only has half of an ALU (Arithmatic Logic Unit), ie. it has no logic capibilities. Well, It has no Operating system, and the clock is stopped most of the time. So the program memory is actually the memory that stores a single program to run, up to 24 commands, each made of 6 bits. This is here a program is stored. To run it, you turn on the clock. It stops automatically, or you could stop it with the stop button, so there really isn't a "start up" or anything like that. As far as getting data into the computer, it is purly manual input, but programs can then manipulate that. The RAM stores any data that can be practically used, and is only 13 bytes, and bytes 10, 11, 12, and 13 are used for multiplication. As a result, there is really only 9 bytes to actually work with. Each of the RAM bytes is a real byte, so 8 bits each. Oh and the 9th pic, That shows the state of all 13 bytes of RAM. Anyways guys, I'm gonna be adding some new things including a totally rebuilt Program Counter and Program Memory with 90 Bytes (each of 6 bits...) to utilize loops, and a 8-bit Comparator for logic-oriented conditional loops. And that will allow for square roots and division! (Yes, I said Square Roots )
  7. Aww, If that was in voltz it could have missiles, which would be really impressive.
  8. Many people take computers for granted, as they use them to maintain their very lives. Few people realize how complex computers really are: This is the Industrial Arithmatic Computing Unit! It was made by me, without the use of WorldEdit, buildcraft, etc. It is by definition a computer. It is entirely made from RedPower Wires, bundled cables, and RP logic gates. I also didn't use any Wireless Redstone. It Contains 17,506 Meters of Wiring, and 1,258 Logic Gates... As in any computer, it is made of several Units, all interconnected by a tangled spiderweb of wireing. The Different Units are as follows: The Adder The Adder is a device that takes two 8-bit numbers in Binary Code, adds them together, then outputs another 8-bit number. 8-bits means that it cannot handle any numbers over 255, and cannot comprehend decimals, fractions, or negative numbers. The Subtraction Units These units, when used in conjunction with the adder, allow the computer to subtract. There are a few of these units, which are as follows: The Selective Inverter: (Diamond Blocks) This will invert an 8-bit number, or not invert it, depending on the state of a separate bit. The Subtraction Unit: (Gold Blocks) This makes the first and only the first 1 bit of an 8-bit number a zero. The Special Adder: (Wood Blocks) This takes an 8-bit number in, adds one to it, then outputs it. The bypass: (Red wool) This allows the computer to bypass these units when it doesn't want to subtract. The Program Counter (The Program counter is the Nether Brick thing in the front, the sandstone is the Program Memory) The Program Counter Is a simple device that outputs a 5-bit number, that increases by one each time it receives a pulse. This is used to keep track of where the computer is in its program. (Like a finger in a book) The Program Memory Yes, those are all levers. They are carefully switched to a binary code in 24 "bytes" of 5-bits each. (I know a byte is supposed to be 8-bits, but for conveinence I refur to any bundle of bits that specifies a single positive integer to be a byte.) These bytes are essentially ROM, Read-Only Memory, that contains the instructions for the computer. The program I have here will be explained later. The Control Rooom Exterior Main Section Looking down the room This room controls the computer. Simple as that. Most of the controls are labeled. In the last picture, all the lamps running down the left side display the state of the 13 bytes of RAM. The last set of levers on the Far wall are for manual input of data into the computer. The RAM If the processor was a person, the RAM would be his scratch-pad where he did his calculations. In my computer, it also serves as the permenant memory for all data. The Multiplying Units These three units permit the computer to multiply. The Multiplication Unit: (Obsidian) This multiplies two 4-bit numbers, and them out puts four different 4-bit numbers. This is done in 4-bit, because multiplication doubles the number of bits. Multiplying two 4-bit numbers, gives you an 8-bit number. The offset Unit: (Cobblestone) This takes the 4 4-bit numbers from the previous unit, and offsets them each by one. So, the first 4 bits aren't touched, but the second, if it was 0011, becomes 0110. 0110, becomes 1100. Etc. The Multiplication Control: (Wooden Planks) This unit tells the System to output the final four 8-bit numbers to the RAM. Then, these four bytes must be added together by the Adder, and then you will have your answer. The Processor Decoders Arguably Part of the Processor, these take the Commands from the Program Memory, and then does something with it. There are 45 of them, each one set to a different code. When the a 6-bit byte is inputed, only the decoder that matches, will output a 1. This will then tell the processor to do.. whatever that bit was connected to. The Processor Itself The Workhorse of the computer. It is remarkabley simply, if not huge. It (mostly) just flips on and off switches. These switches can connect any 13 of the RAM bytes to the first two of the Processors "Buses", and the first 10 bytes of RAM to the third Bus. The first two buses go to the adder and the multiplier, the third is the result that comes back from the adder. By controling this, the computer can do alot. So... How does all this work? Well... Lets go through this simple 11 step program. a =(b + c)- d a = e - d Add a number, then subtract another. 11 Steps, and with a 0.2 Hz Clock speed, that takes exactly 55 seconds. So lets look at the steps. 1) Clear: We want to make sure the processor doesn't have any lingering data on it, also makes sure we are going to add. 2) RAM Byte 2 to Bus 1: Connect the second byte of RAM to the first bus of the processor (Adder Input) 3) RAM Byte 3 to Bus 2: Same as above, but with second bus and third byte. 4) RAM Byte 5 to Bus 3: This adds bytes 2 and 3, and puts the result on Byte 5. byte 5 holds b+c, in our formula. 5) Clear: Resets the processor for a new operation 6) Subtract: Make sure we will be subtracting 7) Byte 5 to Bus 1 8) Byte 4 to Bus 2 9) byte 1 to Bus 3: This last one subtracts Byte 4 from Byte 5, and outputs the answer to byte 1. 10) Clear: Keep things tidy. 11) Done: This command stops the clock, rings a bell, and resets the Program counter. For those who are curious, this is the Binary Equivalent of that program: 100101 001100 011000 100000 100101 100110 001001 010111 100100 100101 101010 Weph! You Don't wanna see the 22 step program to solve the famous y=mx+b formula! O_O In any case, the computer is a Private SSP world on tekkit, and you can't have it. I would like to see any similar computers you guys have made, or anything similar to this (I didn't find anything when I looked... not with this scale) So Happy Tekkiting!
