    Let's build a circuit that displays an image on a VGA monitor! In part 2, I talk about how VGA uses analog RGB signals to send different color pixels to the monitor. I use an EEPROM to store an image and build a simple digital-to-analog converter to generate the color signals to successfully display an image.

    that was deep. Sometimes I imagine I am stranded on an island and for some reason need to make a benchtop mill, or a machinist lathe. All I have is normal clothes. Not even a pocket knife. AND no crashed plane either !! Just beach. I run through all the steps. Pretend I am merely a memory map of evolution. From melted rocks, to perfectly flat surfaces. Huge leaps of technology are required to jump from coco nuts to bolts and nuts.

    Wow, Ben, I'm so impressed with your skill set. Recently, I've been inspired to look more in depth into computer programming. I am currently trying to learn bash and Linux (using Ubuntu) and I'm reading "Linux the Command Line" by William Shotts. I'm perpetually struck with how much I don't know about all this stuff (the more I learn the more ignorant I discover I am). Are there any foundational texts, or books, or anything you could recommend that can help me wrap my brain around all this stuff? It seems so dizzily esoteric ...

    Man, this brought up memories for me. In 1977-78 I made video output circuitry for my 6502 home-built system using almost the same technique. It took me a whole year to get it to work, but eventually it did. Not to mention I had to build my own dip-switch operated EPROM burner (for 2708 devices), to establish my 'operating system' (all in assembler, hand assembled on paper) and countless other tasks to achieve this. Mind you it was only producing a B/W composite video signal via a 2708 character generator, but the timing issues were very similar using virtually the same 74-series you use. My original 6502 got taken apart and the parts re-used for all sorts of experiments when I bought a Superboard II in 1979 and a UK101 later that same year. I wish I hadn't cannibalized my original 6502. I still have a Z80 system however, that I built around 1980 (wire wrapped), but by then I had acquired a terminal and used serial for that one.
    Thanks so much for your excellent videos.

    Black lines could be avoided by adding a latch and clocking it or making it hold the value during invalid data period. Now you can for e.g. add two SRAMs for a framebuffer and a microcontroller for writing data to the banks and make the world's worst home console.

    The Holy Grail for me is to build an 8-bit retro computer built from new, yet plausibly authentic 1970's chips, including connecting it to an 80x25 text display with memory mapped display memory. How to do it? I could try to use a Motorola 6845 video controller, but then I have to buy an old MDA monitor which are scarce and expensive. I don't like that idea. Second method is to do something like this and connect it to a VGA monitor, but that requires a higher clock rates than you can do with logic circuits and a breadboard. Third method is to use an FPGA or microcontroller which I don't know much about and I don't know how I'd do it. I presume a Z80 computer running outside the FPGA cannot directly access memory on the FPGA, or can it? I'm guessing you'd need some logic that continuously copied memory from outside the FPGA into the FPGA's internal memory. Am I on the right track? I know next to nothing about microcontrollers and FPGAs. That whole approach defeats the original goal of using plausibly authentic 1970s chips, but I think its the only practical way of doing it.

    Do you think these components can work with a 75Mhz clock? I want to do the same thing with 1024x768@70Hz timing, which requires a 75MHz pixel clock. One of my goals is to build a VT100 dumb terminal out of a VGA monitor. I bought a 1024x768 VGA monitor specifically to do this, and I'd like to keep it at native resolution, thus the 75MHz pixel clock. I wonder if its within spec of a breadboard to run that fast. I could try to do it with a microcontroller, but I thought it would be more fun and more understandable to do it with logic circuits like this. Now that you've shown me how to do the signal timings, I have a good idea of how to complete the project. Thank you. You rock.
