Honestly looking at a modern CPU from the top-down without having studied it is super intimidating. It's like looking at the top of a mountain and wondering how in hell you're supposed to climb that monster. But everything is just many layers of simpler building blocks, computers are no exception. I never thought I'd end up being interested in electronics like this, but these videos for some reason break things down in a way that just immediately makes sense. And people who only build upwards without understanding the foundations will always breed in instability.

Wasn't that where the phrase "booting the computer" came from? You had to first manually program in a short "bootstrap" program which could read the paper tape reader. The short program would then load in the "operating system" from the paper tape reader and hand control over to it. The process was likened to the old phrase of "pulling one's self up by his own bootstraps" hence the name.

Indeed, excellent video for old timers to brush up on a bit, and newbies to understand it with a hands on approach. Not sure if it was mentioned, but the CE/WE/tAH/tAH/ timings are really only important if using an app/terminal to send a programming data stream, where care must be taken to hold those lines for at least the minimum timing as per the specs. While doing manual programing, the timings are irrelevant, since we can't toggle the switches fast enough to make a mistake/overflow ;) Btw.

Excellent series ! Very well done ! Just a small advice : care must be taken when using RC circuits to generate edge sensitive signals (like clocks and write signals were the rising/falling edges are more important to the target circuits than the levels themselves). In the case or this EEPROM, the datasheet specifies that the falling edge of the /WE signal will latch the address and that its rising edge will latch the data (and I assume start the write operation). In your example, your RC circuit generates a clean and very well defined falling edge, but a very slow curvy rising edge which some circuits may fail to detect as such. In datasheets, you will often find specifications about how quick the falling/rising edge of clock signals should be in order to be recognized.

I dont have word to express about your explanation that you did by using components rather explaining in board and spending your lot of time to present this appropriately without any compromise. I am thanking you to make me well understand of the EEPROM programing. You are well good teacher since you understood how to teach by which way.

This stuff brings back memories of the 80's. Back then PAY TV came out and so lots of folks tried to make their own decoder. The pay system back then was mainly based upon the suppression of the horizontal sync pulses(HSP's), which lead to the TV losing horizontal sync. The HSP's were however still normal throughout each vertical sync pulse. Typical decoder circuits used a PLL circuit to lock onto these remaining valid HSP's, and then inserted proper HSP's back into the rest of the baseband video signal where the HSP's had been previously suppressed. But that is a lot of components. A lot of components pulls a lot of power, so you need a power supply rather be able to take advantage of one that already exists. So I designed a simple line by line decoder instead. It required 1 MC14066B, 1 MC14538B, 1 LM393, 3 transistors, 3 diodes, and several passive components. Total power consumption was less than 15ma. So it was simply installed into a TV converter between the RF demodulator and the RF modulator, and it used the converters +12v power supply. With it being a line by line decoder, there was no PLL locking delay, and no stabilizing delay. Fun stuff !

@atari7001

I wonder if the parallax propeller or the arduino could be used to add the sync, these days? This could have been a remarkably simple method, had the hardware existed, then.

Your videos have helped explain a number of things that I've never understood or fully understood in electronics, especially as I'm just a bit curious as a hobbyist and not something I do in any professional capacity. I love the fact you demonstrate the bare essentials without microcontrollers (which don't get me wrong, microcontrollers are awesome), but there's just something about seeing things done "manually" that really drives the point across and which really helps understand what's going on behind the scenes and is something I haven't come across in many channels. I never knew you could write to EEPROM's so easily, although when you think about it it certainly makes sense. In short love your work, very unique content and I just wanted to take the time to say thankyou. Watching your videos has given me a lot of "oooooooooh that's how it works" moments and has filled a lot of gaps in my knowledge.

A new video! Yeah!

'A' for effort, I'll grant you that. Phew. I can't imagine how much time it would have taken you to put that video together.

Although not as educational, of course.

This video reminded me of one of my greatest "aha" moments in electronics. I was puzzled about how the spectrum analyzer I was using, a Tektronix 7L18, was calculating its reference level, since this was affected by both the input step attenuator and the I.F. gain control. Long story short, they used a PROM to do the calculation, and this was a real eye-opener for me. Thank you for the video.

Used this technique 20 years ago for HNC final year project. I had sine and cosine amplifiers being driven by D to A convertors, the D to A convertors were driven by an EPROM with a clock being driven from a low pass filter being fed from a music source. The amps controlled 2 mirrors which deflected a red laser producing circles, squares and triangle patterns in time to the bass. EPROMs make great look up tables but they are slow and not as quick as combinational logic. Thanks for the trip down memory lane, a very nice video.

I used to watch these as a kid and have 0 clue what’s happening! Now it all makes mych more sense, thanks :)

No words can describe how beautiful your explanation is... this is golden, just building a circuit like listening to a soul music... incredible

Now I feel the urge to buy an EEPROM chip

I really like how you program it by hand! How can I do so with a microcontroller? 8051 for example?

Great tutorial. Watching someone build up a digital circuit while explaining it is so much easier for me to understand than studying a page in a notebook.

You are the one who keeps our interest in digital electronics high Love you😘😘✌

Thank you so much...

Seems like it would have been clever to hook up the display before programming, so you can see it's correct as you program it. Next up, using ROMs to replace the NANDs in your video card?

MAN PLEASE DON'T EVER STOP!!!! I WILL WATCH ALL YOUR VIDEOS AND SHARE IT TO MY STUDENTS!!!

You have taught me more than any other creator. Bravo.

EEPROM: *exists* RAM: am i a joke to you?
