Exclamation The Homebrew Computer Club

Hi All!

I am working on a computer project which may appeal to some of you!

I just started on some of this, and I am looking to see if any people around are interested.

So feel free to stop on by The Homebrew Computer Club

is that like buy resistors and transistors and capcitors from radio shack, spend 3 years, and at the end have a vintage style computer? or buy a video card and motherboard kind of computer. becuase I've don't the second, but the first has been my dream.

It is the first!

I don't consider the second "building" a computer, more like... putting a computer together.

I am designing everything from a processor to hardware I/O... or at least that is the plan... It is a big project.

Looks pretty awesome to me... Good luck with it.

how do you intend to "build" the processor? i mean 90% of me knows it couldnt possibly be on a 65nm scale all packed on a single die, but then again it could be. What sort of scale are talking about? also, i assume at some point you'd be using SMD components, so how would you assemble those to a good standard?

edit: btw, i think thats a great idea overall

Haha, no not a 45nm although that might be a fun challenge .

Processors don't have to be tiny, the one I am designing will be large... very large, like maybe a foot by a foot in size...

Essentially my goal is to design something with the computational power of maybe a PDP - 6 .

I am starting with designing a machine code, and then I will be working on the architecture more.

Edit: as far as SMDs go, I am not sure. I would like to design all the components, but I have heard about processes of getting these things built into chips professionally... I will look into it when I get a bit further in.

hehehe i thought 65nm would be pushing it but 45nm, you have your standards set high

with regards to the SMD components, I meant more in terms of resistors, capacitors, transistors etc not the IC's

and do you have the facilities to create the PCB boards for the processors and other parts?

He only has talent if he builds it and gets it working lol.

I did this kind of stuff some 22 years ago. It's a good challenge but it's a long slog.

At the time i was in to it, i made a machine that could do things other "off the shelf" computers couldnt do. So it was worth making.

Make one today......why?

why do people buy kit cars or restore old cars when it would be far cheaper to buy a new one?

Its just something you'd want to do

ok why make one today ?
well i duno if you have ever felt that satisfied feeling when putting a computer together , such as the build in your sig
imagine that if you had made every single component of your computer as well you would feel a million times more satisfied

anyway i think this would be a great idea of a project however i wouldnt know where to start or anything at all like that so good lukc to you with this and maybe when you finished come back and post pics etc , and maybe offer it for sale

don't get me wrong, it was immensely satisfying when i got it all working. But in those days everything was a challenge.

No computers used the same disk format, protocols had to be written for each machine etc.

Writing multi user accounts/stock control system on something like a BT merlin multi user machine which had about 31k usable ram.......between the 4 user terminals, now that was challenging.


So these days when a computer goes wrong and you don't have to use the oscilloscope and soldering iron. Any muppet can build a pc. I now see why you would want a challenge. Point taken lol

From an old timer who has put himself out to pasture to play games. GOOD LUCK!

lol 2 get 45 nm you need mad expensive equipment
stuff that can shrink and make stuff so small

Thanks everyone for the responses. I am doing this as a challenge to myself. I reached a point where I realized that I potentially knew enough about how a computer worked to design one. So to prove to myself that I could actually do it, I decided to do it.

Pop on by the blog to keep updated!

P.s. a bit of irony here, I don't actually have any interest in building home computers... I have a mac .

45nm is how far the transistors are apart from each other, not the size of the actual cpu!
