For what it’s worth, there were computers before transistors. So really what transistors did for us was to make the computer a more practical tool by virtue of being much smaller, less power hungry, and far more reliable in operation (e.g. no burning out vacuum tubes left and right, no need to constantly tune or tweaks parts to keep it operating correctly). - electromechanical relays -> vacuum tubes -> transistor with a lot of interest rabbit holes like magnetic logic/

++ I always wondered, if they're really a switch, then who turns it on or off, turned out a quartz clock ticking at some billion times a sec (GHz) is ignored or taken into account by some already encoded transistors/memory in BIOS chip, if there is no initial memory/information then transistor would do nothing, as you don't have anything to control them... Manufacturers program a BIOS chip externally and then solder it in on the motherboard.

not very smart, as the understanding of things one man has, cannot be conditioned by the unwillingness of others to learn. in fact, a person understands more than can ever teach, therefore the fact that that person failed to teach, is not real measure of what that person knows. the real state of understanding is limited to the person only, has only sometimes to do with the teaching. Feynman just something that is not really smart. we can talk even more about understanding things, when we acknowledge knowledge is not only compared with some absolute refferencial, but it is also relative, meaning among people who know less, you don't need to know a lot, in order to know more than others. again, Feynman not so smart.

I'd like to use more wood stained 3D printed filament! I want to see that more often.

I like how your code actually sets the control lines directly, instead of running through microcode. It makes it far simpler and, honestly, pretty fun!

Man please oh please go into a deep dive series about this. This is really awesome and one of the coolest projects I've seen in awhile.

I built the exact same computer in a school project. Same components but I didn’t have a 3D printer back then so the case was wooden and I had everything on a single PCB except the clock. For manufacturing the PCB I used a CNC machine which removed copper around the traces and bored the component holes. I loved that project. Learned so much

Dude this content is way too good. Everything here is extremely well executed. You deserve a million subs and a great YT career.

That's truly impressive. Great job at sticking with it despite obstacles and bugs.

Stumble upon this today. This is so cool! One thing is to learn the technical stuff, but your build looks awesome as well. I love the modular design and bus expansion slots. Well done! Subbed!

What an impressive amount of knowledge compressed into one short video!

This video was super useful in my current development of an 8 bit computer😊 When I watched this it helped me understand computers more and how I might design it!❤ And always remember, credit goes to where credit is needed😊

The packaging is so elegant it became my new transition goals.

That's the best explanation I have ever seen, I have been searching videos like this for years, finally found it!

Very nice build! I love its simplicity, the switches and its modularity! Do you have future plans for this project? If you're looking for a newer SRAM, easy to find and affordable, you may want to check the AS6C1008, it'll give you 128KB x 8-bit, it's still manufactured in DIP and it's much faster than the one you're using (less than 100ns access time)😉

Wow! Cold not say anything but "Wow!" You really take all path from zero point!

Saw this today. Brings back memories of a arcade controller I built using the 555 timer, a pair of 74ls193 counters and an eprom. It converted an arcade that uses a trackball into a joystick. But yours is a super cool project. Good show.

This is phenomenal! I love that you cared enough to create the beautiful wooden cases.

You can count binary on your fingers, using each of your digits as a binary digit, carrying to the next finger just as the flip boards at that timestamp. Expressing 4 this way is flipping the bird but you can do it in front of anybody comfortably if they're aware the context is counting to 4.

That’s a 5 digit so every digit that’s 0 doesn’t get added and every 1 does. Reading it from right to left so it goes like 2, 4, 8, 16, 32.. and so on. Every digit gets multiple to the power of two starting from 1 (1^2) because we have 2 selections for every switch “on” and “off”. So 10101 would be 1+4+16=21

No it cannot run doom. For doom you would need a real pixel display. And his computer does not have that. Oh, and also, the controller does not have enough buttons to controll doom. Also x2, the computer does not have enough power to run doom. It also cannot do basic operations like adding, subtracting, multiplying and subtracting. Its only a little project designed to do really simple operations.

Nice and simple design. Thanks for sharing that design!

Cool video, I really love this kind of projects and yours look awesome. Just wanted to point out a transistor is very fast, but it's not even near the speed of light. They have a switching speed, which is defined by it's capacitance and it's shape (size) and it's measured in frequency. If you check the transistor datasheet you'll find the gate delay and it's probably going to have a formula. Also, the wire's in a circuit are not perfect conductors and they have resistance, which makes the electricity move at around 1/3 the speed of light. It's still pretty fast, but not speed of light fast.

So this was a really cool video. I built something similar but it’s only 4-bits wide. I’m interested in the guts of your CPU. What are you using for an ALU and what are you using for the the instruction decoder; are you using microcode to decode or are you using a demultiplexer and gates? My Clock, RAM and address register is pretty much identical to yours.

I just want to say good job. It takes a lot of work to do something like this. Bravo sir.

These Red/Green/Blue circuit-boards, feels like the beginning development of the "isolinear chips" in Star Trek, that allows them to swap out modules of the computer to do other things that are pre-programmed into the chips. (it also feels like modern circuit-boards, like graphics cards & ram cards, but that's not as cool) ;P
