    I don't understand this very well, but this does look cool and fun 🙂

    it could be made much simpler

    Good job i like it, basic processors working

    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).

    I have hand assembled before, but I strongly prefer C# LOL

    I don't understand anything. But i Hope one day i will. I have several computers, and hope one day i will use them to do something better than load windows.

    i have a dream to build like this one since i was a kid, yet, i it still a dream up to now… big thanks for this video
