@redr00ster99 2:23 "16 take 7 is 9. i just said it wrong the second time :)

[ChristianNuts]

save file... PLEASE?

[Salajapaju]

@ChristianNuts follow these steps to get the save file:

1. go to my channel

2. click on the 'brief overview' video

3. look in the description

4. click on the 'SAVE FILE' link.

-and can people thumbs up this comment so it gets to the top?

[ChristianNuts]

@Salajapaju Thanks!

[MrBennubennu]

Oh wait, they're in binary... You'd think i would have thought of that.

[krasykay2294]

well next you need is a computer that much for a caculator imagion playing mincraft on mincraft

[Salajapaju]

@krasykay2294 but the cool thing is that you can program this in multiple different ways. if this computer had multiple gigabytes of memory (instead of 32 bytes), had gigabytes of ram (instead of 16 bytes), and was able to run for billions, if not trillions of years, i believe it could play a game 'close' to minecraft (you would have to re-write the code).

@Salajapaju hey salaja,

me and my friend are building a GPU. we want to make a little OperatingSystem in minecraft (with assembling). the whole thing will be GPU-Based, but we need a decent 8 Bit CPU, too. i could do it, but this is too much work for me alone, because in the end this "Stuff" will be multicore. MAYBE you want to help us? If so, then write me a PM or answer this comment (=

P.S. the GPU is almost done and we will beginn building the CPU soon :)

greets, selle

[ironmaiden947]

anyone else here feel extremely insignificant after watching this? This guy made a god damn cpu in minecraft, while best thing i can do is a wooden hut.

[somebodysnightwierdo]

as if a simple binary calculator isnt amazing enough. you converted it to decimal!

[Salajapaju]

@somebodysnightwierdo i wish i could convert to decimal. it's actually hex (the lazy option).

[TheMattchu1212]

@Salajapaju How does the numbering system work?

[Salajapaju]

@TheMattchu1212 it uses binary. look it up on Wikipedia. when the torch is on, it is a 1, when it is off it is a 0.

[TheMattchu1212]

@Salajapaju Thx. BTW great contraption.

[lemonman93]

omg i got this and i dont know wat to do



[LightLink00]

exactly what kind of math practice do you have. Just stuff you learn in highschool or wat?

[Salajapaju]

@LightLink00 whats does maths skill have to do with it? if you mean computer science, i have a little bit of university experience.

[tiniuclx]

That'ssssssss a nice calculator you have there... Would be a shame if something would happen to it...

[AirasBr]

Yo dawg i heard you like computers!!!!

[jpheitman]

@AirasBr ...so I put a computer in your computer...

[TheMattchu1212]

@AirasBr So i put a computer in your computer so you can play on the computer while playing on your computer

[AwesomeSuperballsX]

@salajapaju I try the add and substract and get FFFF

[Salajapaju]

@AwesomeSuperballsX

did you set the program loader to the 1st line before entering the code?

did you copy the code i used exactly? in this video, i edited out the bit where i enter the program.

remember not to flick the 'next line' lever to quickly. after entering a line, wait a second before going to the next line.

have you tried turning it off and on again?

[AwesomeSuperballsX]

@Salajapaju so for the code 0000111111100001 I must flick the next line lever when I flick all of those on? And yes, I think I used it correctly

[Salajapaju]

@AwesomeSuperballsX have you watched the "RANDOM function" video? in that video i enter some code into my computer, copy what i did in that video, but with different code.

DO NOT COPY WHAT I DID IN THIS VIDEO!

i only edit one line of code, not write the program, that was already done before i started recording!

the "brief overview" video has a list of op-codes in its description, so you can write your own programs if you want to.

[Salajapaju]

@Salajapaju *correction, the op-codes can only be found on the minecraft forums. google "my cpu in minecraft"

[AwesomeSuperballsX]

@Salajapaju thanks man, I'm such a noob. haha

[AwesomeSuperballsX]

@Salajapaju so when I enter the code 0000111111100001, I must flick the next line lever with each of those lines? Sorry man, new to the whole thing...

[nzigen31]

You have a LOT of free time don't you?

[Salajapaju]

@nzigen31 a few hours a day. why?

[nzigen31]

@Salajapaju How much time was needed for you to accomplish this?

[Salajapaju]

@nzigen31 i would estimate between 50 and 100 hours, spread over a month.

[wiliamchen1996]

world upload?

[Salajapaju]

@wiliamchen1996 i'll put a link in the "brief overview" video.

[wiliamchen1996]

@Salajapaju thank you! :D

[Cananatra]

Very cool. Are you using a ripple adder?

[Salajapaju]

@Cananatra no, my added finds 2 results for every output bit, and then when the carry information arrives, it selects which one of the 2 results to use with a 2 to 1 mux. once the first results are known, it only takes 1 torch delay to calculate every two bits after it. so my 8 bit adder takes about 1 second to find the results for the first 2 bits, then only 3 torch delays to find the results of the remaining 6 bits. i'm not sure what it is called.

[Cananatra]

@Salajapaju

That's quite a neat way to do it, I think that's a carry - select adder.

[Salajapaju]

@Cananatra i think you may be right.

[sevevouga]

I built a wooden shack, beat that!

[Salajapaju]

@sevevouga wooden house, ha!

[TomCastCraft]

Now all Notch needs to is like 1/2 blocks and 1/4 blocks then you can get it much smaller :D. One day, it will be the size of your computer!

[bassmanboe]

I can't find my lower jaw

[TheHunterTheory]

You genius son of a bitch. All I can build is a Castle. AWWW YEAHHHH

[JoneKone]

Does the two busses thatt you use to add values go to the registers?

Amazing stuff

[Salajapaju]

@JoneKone yes, the adder takes the values stored in 2 registers, adds them together, and stores the result in another register. that register is then displayed on the screen.

[Setri123]

Amazing. This is brilliant, for god's sake!
