Magic-1 HomebrewCPU Works!

[valveforlife]

When the 37 appeared I couldn't help but yell 'YESS!!'

[Digby0907]

You. Are. The. Coolest. Person. Ever. In. Computers. !.



[w9gb]

Higher resolution video would have been nice.

[Danger9584]

Potato cam! :D

[MrJavaman5]

Are there any integrated circuits used, or are you just using transisters?

[baso88]

@MrJavaman5 Discrete transistors? It would be MUCH bigger... of course he used ICs - it is made out of ~200 74xx TTL ICs. (watch video again and read video description next time)

[thedest1ny]

it looks like it can run gta iv

[heymynameizjoe]

i've always thought i was pretty smart with computers...but i honestly didnt understand like 99% of what you just said here. all i know is that thats pretty damn smart!

[akkudakkupl]

so you plan on building a graphics unit and running some type of DOS?

[tvolala1976]

What frequency is your 555 timer running?

[buzbee1]

@tvolala1976 The 555 timer is set up as a variable speed clock, with a range of appx. 1Hz to 200Hz. During the Fibonacci run, I'd estimate it was running at about 10Hz.

[FusionNinjin]

why dont i have a show me what instruction my computer just did :x

[3mustardMoNkEyS]

Amazing, simply amazing, by the way, do you have a good tip on a IF A=B logic circuit?

[g0twav]

@3mustardMoNkEyS

xor perhaps?

[jvh1gcc]

Absolutely superb. You're a genius. That must have taken unfathomable time and effort to even design, let alone to actually get working. Incredible! I hope you're working in some top-class research centre by now, if not, you should be!

Now THAT'S a computer!!

[plavins1]

thats amazing!!!

[Minifig666]

Amazing work Bill! I assume your output is in HEX not DEC or your computer would be wrong!

[buzbee1]

@Minifig666 Yes - the result is in hex using some slick old HP LED displays (5082-7300 series). Each of the displays has a 4-bit latch and display logic for showing 0-9, A-F. Neat little devices. They are really hard to find, but are similar to the TIL-311, which are easier to find these days (but still expensive).

[Minifig666]

@buzbee1 Thanks for that part link! That will be brilliant for my own TTL CPU (Far more basic than yours). I've designed it using imagined parts and now I'm trying to find them in the 7400 series. I tried telneting the Magic earlier but could not work out to move up a directory to get into the games from usr/home.guest. How do I? Thanks in advance!

[mrpokemaster2k10]

i want to bulid this

[williefleete]

this is absolutely amazing.

[thedancinzerg]

wow this is awesome

[tututu224tb]

Ok, when can I start playing WOW on it?

[kingcrimson234]

can it run crysis?

[ssegabriel]

if it doesn't run windows doesn't have a reason to exist

[bedeone]

@ssegabriel iPhones, every current console (X360, PS3, etc), and several others don't have a reason to exist?

[cargoterm]

Microsoft hires people like this CPU maker. And it is happy to rip off people like you.

[zhopenza]

@cargoterm Hope you meant Intel, not Microsoft :P. I wish I picked this kind of crap up as a hobby, would of made Electrical Engineering much easier (though more boring). But really when you look at what a CPU really is - it's amazing how much comes out of putting some impure silicon together and sending some current through it. Digital design is for the win.

[BannanaOfDoom]

ssegariel, your such a big fag..

[Circuit6040]

Bravo! Very impressive! I have no doubt that you have read the book The Soul of a New Machine by Tracy Kidder, which as you know, tells the story of the Herculean effort necessary to develop and successfully construct such machines. If anyone out there wants to truly understand the significance of what Buzbee1 has accomplished here, you absolutely need to read this book. Thank you for keeping this art alive.

[heatflash888]

Now all you need is to be transported back to 1970 and you can out compete hewlett packard and ibm.

[Fangornmmc]

That must have been awesome! Having a machine you designed and then...bang...it works! Cool. You inspired me to do the same, i'll start this year but I don't think I can beat yours...I'd be happy if i can calculate 1+1 on it :P

[xbiosparkx]

Actually very easy. Read up on half adders, or SR flip flops.

[Fangornmmc]

@xbiosparkx

Yea I ahve done so, I am waaay further (not further then the magic-1 but in experience i mean) then before! I (think) I understand All logic gates, Flip Flops, EPROM, EEPROM, SRAM, DRAM, PIC's etc...

Oh and I finally got how the transistor works that really was like a eurea moment, All the pieces of the puzzle fell into place...

[kakureru]

load some ferrite cores up with some mp3s and go fo a jog :P

[stickysausage]

Geek! (i mean that as a compliment) I wish i could even grasp the concept of how software runs on hardware at a fundamental level. I understand the basics of both, but the link between the 2, im lost.

[joker71496]

reminds me of an 8800

[Boztalay]

High five, man. I'm hoping to start a project like this this summer.

[asassinoooo]

this is great, it shooted me back to 70's 80's and the great homebrew computer hackers generation!!!!

[cyberlord64]

you sir are officially my hero.

[boxa888]

ur the best, i wish i could do that! amazing!!!

[jojje302]

TRhis is a real computer. I like it!

[ciucinciu]

i dont even know what are you doing, but it;s very awesome

[blackcastlesoft]

this machine is really amazing! the only thing I'm confused about, unless I'm completely mistaken about the Fibonacci sequence is that 37 isn't part of the sequence.

[blackcastlesoft]

oh wait i just realized it's in hex. my bad :/

[abresas]

37 hexademical = 55 in decimal, which is the 11th fibonacci number

[RichGilly]

Hardcore!

[kal9001]

If you read the website you see that the Magic-1 doesnt have any video out, To opperate it you ether need the test board he is using there, or you use Telnet from annother computer.

This thing is amazing, I admit my knowlegde in this field is limited but growing steadily and hopefuly one day I will understand and be able to fully apreciate this creation and do something simmaler myself.

[posixoptions]

The videos of the Magic-1 are probably the most inspiring and amazing (in the context of computer science) on youtube -- this whole project is just so amazing it blows my mind away, that you actually made this machine work is just fantastic stuff, fantastic indeed.

I saw you had a CRT connected to it in one video, was that a terminal or did you implement a framebuffer display or equivalent?

Congratulations on the whole project, I hope sincerely you will not stop at Magic-1. :-)

5/5.
