content: A guy makes 8-bit computer on his breadboards, using just digital logic.I.e. No Microprocessors or Microcontrollers used. Just digital logic chips.Unfortunately/sadly there is not as much details, such as schematics. As I would like, at the moment. (As far as I could tell).For more videos, please see his channel:https://www.youtube.com/user/eaterbc/videos?flow=grid&view=0&sort=p

content: Quote from: iaeen on January 18, 2017, 12:45:28 amYes, I've also been going through more of his playlist. ItDOES, gradually shed more and more light (from what I've seen so far), on the details. I'm rather impressed with the quality of his presentations, overall. Even though he is discussing stuff which I already know tons about, and don't really need to know much more about. I find it very entertaining to watch and refresh my knowledge.I'mFLABBERGASTED, that its sum total of program memory and operating (for variables) memories total 16 bytes!But that allows its 8 bits, to be split into 4 bit instructions (up to max of 16), and a 4 bit parameter nibble. Which so far seems to either be an address (within its ginormous 16 byes of address space, 2^4), or a 4 bit immediate number parameter.Yet it is enough for somewhat complicated (demonstration) programs such as Fibonacci series, on a really, really cute blue LED seven segment display.I wonder what his background is. If he details it, I've not seen any mention about it yet.Just to put it into amazing perspective.The total program and ram for variables space = total of 16 bytes.The (not yet released), Intel Skylake EP (upcoming server processor), will hopefully have the latest SIMD instruction set called AVX-512 (AVX3 was the old name). Which will effectively give it a maximum accumulator size of 512 bits = 64 Bytes!tl;drSo the latest (when released Intel server and probably later domestic) cpu will have four times as much "ram" per accumulator (SIMD accumulator/registers) than his computer. Which is just amazing!
