Hugged to death. See [1]. [1] http://web.archive.org/web/20190516084513/http://mycpu.eu/

In the age of GitHub pages, Netlify and who knows how many other unlimited bandwidth web hosts - how on earth do people still manage to get their sites slashdotted?

By intentionally serving it from a computer that’s essentially from the 70’s

This is definitely on my "list of things I've always wanted to do but I realized man is mortal and I have to prioritize". I'm a personal computing enthusiast and it doesn't get much more personal than designing and building your own architecture.

Before I saw the German, I already had a feeling it was --- I'm not sure why, but I've seen Germans use that style of page a lot (another example: https://www-user.tu-chemnitz.de/~heha/basteln/PC/USB2LPT/ul-... ). That and the encouragement to build one yourself stood out.

This one looks very similar to a 6502, and seems to be much smaller than another semi-famous discrete homebrew computer, http://www.homebrewcpu.com/ --- that one only runs at half the clock speed, but the performance seems comparable.

Amazing! A computer made without microprocessor... or a processor made of TTL circuits. He has remade a system similar to the core of the great 1970's Xerox Alto / Xerox Star series :-) I never thought someone would remake a processor this way. I love that kind of madness !

https://hackaday.io/projects?tag=CPU (Some are FPGA, most are TTL) Including two risc-v implementations (one seems stalled):

One I am particularly interested in is the Gigatron:

I did this for a living in the 1980s--CPUs from TTL. My artistic side wants to build a small running computer from all TTL inside a plexiglas cube with all the chips glued to the walls and the interconnecting multi-colored wires exposed with a small display of something.

Ben Eater has a most excellent Youtube series in the same vein.

https://eater.net/8bit

He even sells a kit with all parts and schematics included. It's easily one of my favorite projects of all time and has inspired me to continue learning more.

It's not close to MyCPU's level of complexity but is great to get you started.

http://www.homebrewcpu.com/ is wire wrap 16 bit computer that in fact serves the web pages and has telnet access.
