Linux takes 4.76 days to boot on an ancient Intel 4004 CPU — CPU precedes the OS by 20 years
In essence, to bridge the hardware/software divide, the enthusiast emulated the more capable MIPS R3000 processor, which boasts the required C compiler support.
As long as they can talk to external storage, which I expect all of them can, all of them can probably emulate each other, so all of them can probably boot Linux.
Well, at least one is an FPGA not an SOC…
It is NOT portable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that’s all I have :-( - Linux Torvalds (1991)
I’ve never heard of this “Linux” thing but it sounds like it doesn’t support any of them 😤
