34 پاسخ به “در داخل کامپیوتر (EDSAC) – Computerphile”

1. Why didn’t they use oil instead of mercury?

2. Back in the days, someone on the EDSAC team suggested an EDSAC watch, but the idea turned down.

3. Anyone who has programmed in assembly language can really appreciate this explanation.

4. He's a bit inaccurate early on. Technically all computers are symbol manipulators.

5. They have been working on this for 5 years. I wonder what is the state of this machine in 2018.

6. Andrew Herbert talks like prof. Poliakoff

7. There always seem to be new Computerphile episodes that I haven't seen yet and must watch! Such a great channel!

8. It's insane that this was once state of the art and now my TI calculator can probably do the same stuff EDSAC could do.

9. Mind equals blown.

10. i just love this kind of videos about those very primitive computers, they always make me excited about building my own…
    I mean… they make it look so incredibly simple… it makes me wonder if it actually IS that simple

11. Listen carefully and you can hear the characteristic clickity-click sounds of the WITCH computer in the background.

12. built like a thinkpad – totally modular and user servicable while also huge and ugly

13. The boot device mentioned at about 9:50 looks like an old analog telephone switch known as a Strowger switch.

14. A five foot long tube about 2 inches in diameter to store 32 bits. How big would a gigabyte be?

15. Mmmh pizza electric crystal

16. I can hear all the audiophile weeping about those vacuum tubes being wasted on a museum piece 🙂

17. This fascinates but I don't understand computing 🙁

18. When I was working in a telephone exchange in the 1980s, we had selectors like you can see from 8:20

19. So they had 36 bit computing back when this was built. Only 8 or 16 bits in the 1980s

20. WOW! I haven't heard anything of EDSAC since Computer Studies at school in the 80s… and here it is!!!

21. Your cameraman is useless; if he's not zooming in and out, in and out, he's wobbling all over the place and doesn't dwell on a subject long enough for us to take it in. Get a new cameraman please, or teach this one BASIC skills.

    Super videos, thank you 🙂

22. 250,000 dollars?
    Better run 400,000 windows of Battlefield 4 and ArmA 3 on Ultra at 9,000,000,000 FPS.

23. It's like looking at the first PC ever being built by a bunch of college age nerds. It's beautiful, especially the veterans there.

24. I wonder how powerful a computer would be if engineers used the same design philosophy they did back then.

25. so, the echo device used by guiter players could be a .. delay line ?

    aha… that boot-selector pulse system – is that comparable to the dail-in system of phone systems – i know that it will generate the 0/1 effective a program that tells the system what to do.. first, next and so on – but – that ring pulse system looks so.. alike the phone number selector.. – just at glance.

26. Love it! Any estimates on a completion date?

27. Hmm, what would emulate those delay lines I wonder.

28. Would they have used banana plug wires on the original? Those look suspiciously like banana plug ports.

29. Utterly fascinating. Love it.

30. but… can it run minecraft ?

31. Holy Hell, I just want to ask the gentlemen in this video "What do you know that I don't?" and sponge off their wisdom and experience.  I hate trying to figure this stuff out on my own.

32. I know you are Brits, but could you make a video on the Zuse Z3? 🙂

33. I am oddly surprised and impressed that it had hardware for multiplication.  I can recall when building simulated processors it was often easier (far fewer gates) to handle it in software instead.

34. Very fascinating, the passion these people carry is truly magnificant. Really great to see this. A work of dedication and progression. It would be great of these people would publish a book in which each one involved in this build tell their about own assigned task and contribution within the line of the total assembly procedure. Within this publication it would be wise to include in-depth building/assembly schematics. Thank you for showing this.
