Nice video !!! Thank you so much

Thanks Dr. Plaque. Don't forget to floss your beak.

A good stepping interface would be two buttons, one for 'up' and one for 'down'. Pressing DOWN repeatedly generates a stream of positive pulses (__--__), UP likewise a stream of negative pulses (---__---). Alternating the buttons gives one edge then the other. Logic for UP: If already up make a negative pulse, else just go up. Pulse time set by underlying 'run' clock rather than a monostable.

Hell yeah Dr Plague!!! keep em coming!

Makes me wonder how far it can be taken since old processors are not made anymore, this might be what computer hobbyists have to do. Looks like a pretty good computer could still be made.

Yay :D

Cool vídeo!!

I thought that was JS Bach! I watched on full screen the whole video

I like your way of explaining things. Simple yet detailed.

I predict a Ben Eater style clock source. It is a very nice and simple clock source and scales well up to 4 MHz range. Edit: Nope, I was wrong. Refreshing to see an alternate approach.

cool.

If I were a rogue class I would steal you an atomic cesium clock just so I can see a Plague doctor taking it apart and explaining it.

This is actually really good vid, need to figure out what half lines and equalizing pulses are

If you think wearing a plague mask discredits him as an engineer then you clearly have not been in enrolled in an engineering course ever

was trying to figure out where to start with a rare faulty video output signal on a console and this is the absolute best thing I've ever seen that explains the why's of circuit signal design around this stuff. It is great to understand 1% more about any of this stuff today. Thanks so much man.

Excellent video, thank you for sharing!

I had seen Bach next to the multimeter! I was second guessing myself since it seemed to me to be too obvious.

Hellllo doc

Awesome lol

Problem: I cannot focus on the video content since I'm desperate to find Bach all the time :)

I saved this video for the future.. so i can explain how the plague looked like..

Nice! Best regards from Brazil!!!

Judging by just these few pages shown in the video, it might be a nice book. I've just looked for it and the prices are out of outer space and beyond. Impossible, unfortunately.

Great Awesome video!

I loved Floyd's electronic devices book. The format is so pleasant to use.

The digital nature of modern computers are highly dependent on the time base used, no digital component is actually digital with an instantaneous transition. But rather very fast rising and falling edges.

Great work ! Do check out - "THE GRAY-1, A HOMEBREW CPU EXCLUSIVELY COMPOSED OF MEMORY" its a phenomenon demonstration of how to design combinational and sequential* circuits using ROMS. similar to your rom Counter. Cheers !!

Yay! :D

This clown keeps obstructing the view, so no really possible to see the information properly

-"Sometimes I wonder too!" 🤓

About magic, my version is: your processor is not genuine Intel 8088 (HMOS tech 3 micro), many copies on aliexpress based on new maded CMOS chips, PLC, etc.

i8088 it is 16-bit processor with 8 bit data bus.

Junior electrical engineering student here, thank you for making these videos. They are very informative and I especially liked your series on composite video signals. I made a flash memory programmer back when I was in high-school using an Arduino uno and a chain of flip-flops, I actually programmed the exact same chip you have in this video. I would love to see another video on the software you programmed for this project(unless its later in the series). Thanks Dr. RG Plague!

You are awesome Dr Plague, is your code available some where for me to access? Keep up with the good work, looking forward to the next video!

Dude WTF? 🤣

Will it have interrupts? How do you plan to take inputs into the CPU?

i'd love to see this slowly turning into a bigger project someday.

The anticipation is building! Love it. Thank you.

Ghost hunting video when? 😊

It could have just been something as simple as their database being down. They probably don't have someone on standby to fix that sort of thing these days.

Hi

Wow! You do something very special in my opinion, delivering proper detail while being entertaining. Freakin awesome!

That's why my simulator (which is basically interactive Verilog+schematic hybrid simulator) is built to simulate timings and detect violations from the ground up.

Yay!

Doc, that was incredibly clear and compelling. Well done! I'll be interested to see if you head towards RISC with hard-wired control logic or towards a microcoded design. As you developed the Mark I here, I kept thinking that it looked a lot like a microcode sequencer. I'm looking forward to the next installment!

You earned yourself another subscriber. Love these types of videos.

Excellent, Doctor Plague ; Logic circuits first ! A long time ago, there was a Radio Shack kit that worked on this principle. It took me a long time to figure out how it could work 🐣 😅
