> If you're skeptical that this feat is possible with a raw 4004, you're right: The 4004 itself is far too limited to run Linux directly. Instead, Grinberg created a solution that is equally impressive: an emulator that runs on the 4004 and emulates a MIPS R3000 processor—the architecture used in the DECstation 2100 workstation that Linux was originally ported to. This emulator, along with minimal hardware emulation,…

...and also a lot more practical than writing a C compiler that can compile the Linux kernel (not to mention other tools that you might need) for the 4004.

However, one major issue with this (aside from the slow slow speed) is the limited RAM - I assume this requires lots of swapping from the SD card to work?

I mistakenly think the guy took over a year to boot Linux/4004 due to the comma in the post title. (I was aware that comma represents decimal point in some regions, just didn't get this in the first place.)

Also the comma would be after 3 digits, no? Like 1,000 and 100?

Check out what they do in India[a]. It's not beyond the realm of possibility to misremember it exactly.

Commas are used for the decimal point instead of the period character in many countries, including many European countries.

We do, but most of software engineers out there hate it and use the dot, for obvious reasons (CSV in particular).

Having said that, I like our Swiss decimal group delimiter: 1'000'000.

I'm from one of those European countries and still also read it as it taking over a year to boot...

Yes, in India we use 3 places for the first and then 2 places for the rest. But comma was never a thing. Fun fact: In India we use upto Crore as mentioned in the link, but recently had to learn upto Lakh Crore as the politicians looted bigger recently and went beyond normal. :)

Unless the title is internationalised somehow (possible, but I doubt it), it's "4.76" in the original article. That's what happens when submitters editorialise ;-)
