Wow, just wow. So cool to see an 8bit computer built using bread board. You are a good teacher. Good way to teach how CPUs works, something majority of us take it for granted.
I would liked to have him as a teacher while taking my Bsc. I never enjoyed programming a cpu, he made it seem so cool after only 17 minutes (both videos)...
I graduated as an electronic engineer from the university for 10 years. This is my first time really witness how a computer works. You are awesome, thank you!
I love this hands-on way to learn code by building! Even the instructions are loaded with DIP switches without use of any software. You are an amazing teacher. How did I NOT see this video before?? The best learning materials are like this rare, free and hard to find! Great job! Thank you!
THANK YOU for sharing your knowledge with us! I have a background in electronic repair but was only shown very basic info on how computers work. The reasoning behind it was that we maintained a switching system interface which tied remote radios to operators in ATC environment. Absolutely fascinating…I would love to build something like this.
I'm taking a computer organization course at a university right now. This video offers a great tangible method for seeing how some of these fundamental components work
Brilliant Computer!!! it came up with "42", and as everyone who's familiar with the "Hitchhikers Guide to the Galaxy" by Douglas Adams knows, "42" is the, "Answer to the Ultimate Question of Life, the Universe, and Everything", calculated by an enormous supercomputer named Deep Thought over a period of 7.5 million years. Wonderful Achievement Lol :-D
I love your videos and I always recommend you to my friends, was linking them to this video and the opening hit me again and I can't help but laugh at "very simple program", you do an amazing job at explaining it in a way that is simple to understand but the amount of setup and work it takes to program something like this compared to a lot of other things just comparatively makes me laugh XD. But honestly as always your work has been and I see no sign of it not being in the future amazingly great.
I wish we had this plus another hour of in depth explanation on the electrical part of it, etc. This was pretty in depth as is, but it leaves me with so many questions
I am an undergrad CSE student from India and I don't know how much should I thank you and that super great randomness that brought me here to your this video. I have learnt these concepts during my classes, but today I have got such an amazing, awesome, super super contempt feeling of computers that I don't have words to say :) :) Thank You So MUCH !!
Great! Reminds me of the days I used a 6800 in an embedded controller. And the PDP11 where we had to enter the boot loader in RAM with exactly these switches and LOAD button. I wonder how many people nowadays realize that the Address and Data LEDs on your board are actually the Blinkenlights on computers in (older) movies. And I see you still use Gefingerpoken to get the program into RAM!
I have been looking for this level of education on how computers really work. Thank you! I would like to see even more background on how this computer was made and works. Ultimately I would like to see this level of detail show how more complicated things work, like the visual of a football being "thrown" across the computer screen.
Awesome - this project together with the visual 6502, and the various 6502 deconstruction projects have given me so much more appreciation for what happens on the bare metal of a processor. Guess what everyone, it ain't magic - it just takes some very clever engineering to get all of the components working together in the right sequence.
Excellent, this is exactly how I wrote my first assembly language programs for the cbm 4032 back in school. In the breaks, we would rush down to the computer room with large sheets of hex groups to type them in and see if the program would work.
I took a semester of assembler programming at university years ago, I just wish the course would have started with such a brilliant, informative and entertaining demonstration.
I am absolutely in awe. You are so good at making this understandable. You've given me a strong desire to make this myself ... that's a bad thing because I already don't have enough time! lol.
I am a CS grad student and always wanted to, but never built it. Recently got my hand on some hardware and I'll go wild with this playlist! Thanks Ben!
It's useful to break it into smaller pieces, to look at the microarchitecture in two categories, data flow and control flow. Once you understand that the bit pattern for the instruction corresponds to control lines, it becomes much clearer. Also don't forget the stored program concept, the instructions for a program and its data are stored together in memory as numbers which can be easily manipulated. If you learn this you'll be a very useful person to know and more importantly, to hire
Great job. Obviously your computer runs in real mode (program and memory address locations could override each other) It would be interesting to see what happens if you try to read a program instruction address as data or vice versa. Keep the videos coming!
And in nand2tetris, you not only build a 16-bit alu/cpu and 32k ram, you also build the assembler, vm translator, compiler, AND an os to make a game you code up in the computers own high level language run! It's as "from scratch" as it gets.
@@Cardgames4children Yes, I wonder if this channel author knows about nand2tetris. I made everything and got to making an assembler but failed at that because I couldn't debug my low level C assembler :D
@@Cardgames4children i made this kind of project about 20 years ago and all was my own design, not a kit. Lower lever would be making all components and wires by yoursef using raw natural materials.
I am currently studying for the GATE examination (Considered to be the toughest examination in India) where I have subjects based on microprocessors and its Architectural study.. Your videos really makes my concept clear and its really amusing to watch something so discrete working individually that we have to learn on the paper. Thank you !
A) amazing project so cool to see the parts working together I wish they would things like that in school. B) You explain so well and you don t have an indian accent bless the lord. Subscribed !
Barack jong-un at least here in germany, all this is significant chunk of computer science at university. you cant really understand code, without knowing all this.
Mein "I did" bezog sich auf die Aussage von Barack jong-un. Ich wollte sagen dass Ich "Computer electronics" im Informatik Studium gelernt habe. Dem was du geschrieben hast stimme ich zu ;)
This is what I call TTL madness. I love it. I've been making TTL control circuits for years. I never needed a microprocessor. LOL. A couple counters a few nand gates an occasional shift register. Walah!!!
if it outs the result value from ALU and re-input in A register at the same time, it is like chain LOOP and sum the total as new input value and SUM again, and again, without control, unless, ALU support to lock its output result o pre-buffer its inputs, or you insert a controlled buffer in the middle.Or do sum in the rising edge, and present result in the falling edge.
Awesome man...... i don't know what to say....its really very very hard to do what you have done.... i have been searching for someone (in years) to teach me how to make my own computer and programming language. But my problem is that i have the SCIENCE in my heart and Commerce in my degree paper. So i, myself self taught to learn Science and Computers. Your video have given me a lot of inspiration and to learn some very basic concepts.
Great video series..!! It's not reinventing wheels. But I do believe that UNIQUE videos of these kind will definitely add fuel to the FIRE of young minds who wants to think differently and come up with better inventions. Great work Ben... please continue the same. Science grows leaps and bounds when some one comes back and question the very basic rules ... Many have done it in the past ...Newtons laws were not the ultimate ones... Many great minds like Einstein proved that they are subsets of the real picture.. Good job carry on please.... Thanks, Sail
I'm going to finish my arm cpu,it's just need three transistors for a processing units including the isa executive,comparative.i use the matrix memory from 2 ic 4017 for containing the isa codes and one to count the bit.the memory will open the suitable i/o port when it scans to a code.
I thought of a way of storing programs by making the computer programmable through an optical reader. You could also expand the memory and program counter without having to change too much of the structure by logically dividing the memory into 16 "pages" of 16 bytes each. A "JMP" to another "page" would always start the program at address 0 in that page, so the instruction would be "JPP" (JumP to Page) and a 4-bit page number. That way, the main bus can remain at 8 bits since each instruction is still only 8 bits. What I thought of was a 10-bit optical reader. 8 bits are for data. One bit is used to change the address for the data and one bit is used as an index bit, to signal that the data is ready to read. If the address bit is set, then the 8 data bits are loaded into the address counter for the reader, otherwise the data is loaded into the current memory address and the address counter incremented. A 1 bit would be two extended ASCII code 219 characters in the same position in successive lines. The index bit would be an extended ASCII code 220 character in the first line with code 223 directly underneath it. A 0 (zero) bit would be spaces. Using code 220 with code 223 underneath it would make the index bit smaller than the other bits, so the other bits would be sure to be set up correctly before the reader sees the index bit and reads the data. If the data is "clocked" in on the leading edge of the index bit then the second line wouldn't be needed, making the data even more compact. A monospaced font (not a kerned font) would be required to keep the spacing even, and there would need to be no spaces between lines. The code would start with an 8-bit address with the "address" bit set (and the index bit of course), followed by bytes of data with the "address" bit clear. If you construct the reader so that you can move the reader head across the paper to align it with different columns, you can store an entire 256-byte program on 4 sheets of ordinary printing paper. In most cases it will take less paper, since most programs will be shorter than the maximum. If you use leading-edge clocking, then 2 sheets would have enough room for a full program (printing double-sided isn't advisable in this case, for fairly obvious reasons).
This tickles the nerd in me just the right way ^^ But with just 4 bit for parameters, longer programs all have to start with "0x0: JMP 0x10" so you can store your variables and stuff in memory addresses 1-15.
Wow, just wow. So cool to see an 8bit computer built using bread board.
