Marks256 said:I wan't to design the mobo, and the components. I all-ready have mastered building PC's from the allready manufactured MoBo's, CPU's, ETC. I would like to build a computer from scratch. I will philba said. I will read about the components, and how they work. If i have any questions, i will post them here. I really apreciate the help, exept for hero999's advice. Also, Hero999, i said i was short on cash, because i spent all my $$ on my custom made computer(built from the ground up by me). Here are the specs:
AMD Sempron 2800+ (1.6ghz)
nFORCE3-A MoBo w/ 1.6ghz HT FSB
512mb of DDR400 Kingston RAM
AGP 8x
8 USB 2.0
DVD-ROM
CD-RW 52x32x52
nVIDIA GeFORCE 4000
C-MEDIA 5.1 surround-sound sound card
Windows XP PRO w/ sp2
350watt powersupply
Shall i go on?
GOD NO! That would be suicide! I was just showing Hero999 that i did make a system from pre-manufactured parts.I did not understand why did you place your computer specs here.
You want to build a computer from scratch, similar to your sempron 2800+ (1600 Mhz)? Using 8088 (2MHz) /8086 (10 MHz)?
I want to build a fully functioning system around the 8088/8086(havn't decided witch one qite yet). I just want to learn how a computer works, and see if i can build one too. I want to build the circuitry to the RAM, Boot ROM, ETC. Then keep building things up on it, just to see if i can. If we can get it to work, we will also try to put an IDE Drive on it too.Define better what do you mean by saying "scratch":
Yes. I couldn't have said it better my self. I won't build the processor yet. I will save that task for when i finish this one! I will build up the system arround one of the two processors.1 - You want to build all components (like mems, processors, the north/south bridge, the storage devices...), so you gonna create your own computer standards (like Apple/PC standards).
Kinda. I will just use the processer, then buy a crap load of components from Jameco.2 - You want to use comercial components, like components from VIA/SiS/NForce/ATI/INTEL to build the mobo, memories, etc. You gonna use a comercial processor, storage devices...?
I'm not sure. If not, then this will be a fun learning experiance. I guess this will give me a chance to learn what i may not allready know.Do you have enough electronics knowledge and experience?
No. It is fully explained in one of the books i am going to purchase this weekend.Do you know Assembly?
I know how digital works, but i don't have every chip memorized. If i have any questions, i will post.Do you know how digital devices works?
Ahh, no. What is that? Chances are i do, but i don't recall it at the moment. Will you leave a small description?Do you know the computer theory?
Not off hand. I will get them within due time, though.Do you have the necessary machinery to assemble the components, the PCBs...?
I am in the middle of finishing my homebrewed Logic Analyser, i just need to write the software. I do not have an Oscilloscope, but, if i can get a job next year, it will be on my very, very long list of things i need.Do you have the necessary equipaments to test the computer components (Logic Analyzer, Oscilloscope...)?
MONEY: No. I will just through in some when i get cash. I have alot of components i can desolder.Do you have enough money and time to spend, designing the computer?
I don't know. I guess we will find out, wont we?Do you have enough pacience to withstand the failures?
True computer? I think you mean true PC (don't diss microcontrollers!). Just because it's embedded or something that is not sitting on a desk with a monitor and keyboard doesn't mean it's not a computer! That thing sitting behind your eyes is a computer that kicks the ass of every manmade computer on the planet.Marks256 said:I do not want to use a microcontroller. Then it wouldn't be a true computer.

Marks256 said:I DO NOT THINK THIS WILL BE A POINTLESS PROJECT! My favourite saying is "An education is worth more than any sum of money"! I would rather save $400 now on learning about this stuff, than have to spend $5000 later for college.
Marks256 said:Ok, now you people are trying to discourage me! I don't like it. If i have to i will go find a more supportive forum community. I knew if i posted how old i was, all you people would do is try to talk me out of it. So what if i don't know the relationship between the clock and trace length? I will learn about it if i need to. This is what is wrong with society today! People have no faith in people. Back to may age. The whole reason i came to this forum, is becaused i googled "Homebrew Computer". I clicked on the link, and it came to one of the treads, similar to the one i posted now. Guess what? The responses were endless! People helped in any way possable, NOT trying to talk the poster out of making it. I expected the same response, but NO! You people are so set on thinking that since i am "nothing but an ingnorint highshool studend wasting his time on something that is not achievable for his age", that i don't have a chance in hell of compleeting this task. How do you expect me to learn, if i don't try? Huh? So maybe i am "Jumping the gun", but i didn't know of any simpler processer to build arround. Perhaps if i find something on another processer, i will give it a shot! But i would REALLY apreciate it if you people would be more supportive. Since nobody will help me, i will just start on my own. If the book i get is truly worthless, then that is my problem. But if it helps, and i am able to get somewere, then i say; maybe the younger generation is alot more capable than you would imagine.
Not a clue.Do you know what is pig capacitance or pig inductance?
I think i experience this once. Doesn't it act like an antenna? Producing noise?Do you know how high frequencies behaves in PCB trails? And in a round conductor, like a wire?
nope.Do you know what is impedance?
This i do know. Baud rate is bytes/sec.Do you know what is a baud rate?
oh god! I don't know this one either!Do you know what is modulation? And what kinds of modulation?
Sort of...Do you know how electronic memory works?
Not sure?Do you know how a memory stack works?
[starting to cry;] NO!Are you able to make a microcontroller program from scratch?
