You can't.

Are FPGA's low tech enough?

>>869852

the goal is as low as we can go, so for any component we think of what is required to make it, then whats required to make that etc..

ill look in to that.

>>869848

I'm not saying it can't be done, but you can't do it. Feel free to prove me wrong anytime.

>namefag can't use the sticky

wow!

>>869854

You could do the computation by hand by making a pencil and paper from scratch.

If you want a somewhat practical digital computer (as opposed to a human computer) you don't really want to go below the level of FPGAs. I consider stuff like CPLDs to be on the same level for example.

Communicating to FPGA through UART isn't a desktop computer.

>>869860

Are you saying that it isn't a desktop computer if it isn't IBM PC compatible.

>>869866

Yes. If OP meant 8-bit console based hobby toy, that's a completely different issue.

What is your background?

>Do you understand digital design?

>Do you know a HDL?

>Are you competent in a low-level programming language?

>Do you understand any assembly languages?

>Are you familiar with operating system internals?

If you answered no to any of these questions, you're not ready to build your own desktop computer. You could get away with building the OS if you were capable or mirroring an existing architecture supported by an existing OS, but this would likely be more difficult than writing a simple bespoke OS for your custom architecture.

OP's race, ethnicity and gender are also highly important here too. Only the whitest of the whites can aspire to this level. To my knowledge I have never heard of a woman design an operating system so that may be a factor, but it's not as important as possessing master race DNA.

>>869857

This. It can be done, but just not by OP.

It is possible. look at what Steve Wozniak did with the apple.

>>869994

Woz took a bunch of off-the-shelf controller chips from hobbyist suppliers for teleprinters of the 1970s and assembled them into a working computer

I think OP wanted to somehow design and fabricate the ICs themselves from scratch

> OP wanted to somehow design and fabricate the ICs themselves from scratch

Holy shit that's funny

>Grab some sand

>Sift out the silicon.

>Melt the silicon and cool it into a cylindrical cylinder called an 'Ingot'.

>Slice the ingot into individual disks

>Buff it a little bit to get a nice polished surface

>Use Photolithography to imprint your circuit pattern onto that disk, you'll want to apply some photoresist to the surface.

<If you don't know how to do the previous step, you're not cut out for /tech/

>Shine some UV light on it

>Use some chemicals to remove excess photoresist

It's pretty easy from here onwards.

That only works if you own the land the sand came from.

If you wish to make a desktop computer from scratch, you first must invent the universe.
