Working Linux on Unmodified NES {Hardware}

Linux has many benefits, however it’s particularly well-suited to working on older {hardware}. There are very light-weight kernels on the market that don’t want a lot energy to run — particularly in case you’re 1337 sufficient to work solely within the shell and don’t want a GUI. Have a 30-year-old PC gathering mud? It’s going to run Linux, no drawback. However what in case you have even much less horsepower than that to work with? To dunk on each different working system on the market, DeCrAzYo proved that it’s attainable to run Linux on unmodified NES {hardware}.

That’s really a lie — however we’re solely passing on DeCrAzYo’s lie. This isn’t actually working Linux. As a substitute, it’s working what DeCrAzYo describes as a “Unix-like working system.” Sadly, even Linux wants extra sources than an NES has to supply. However that is shut sufficient that we hope you’ll forgive the misdirection.

Particularly, DeCrAzYo selected to run LUnix (Little Unix), which was developed for Commodore 64 computer systems and acquired its most up-to-date replace (Model 0.21) manner again in 2004. LUnix is good as a result of it’s ridiculously light-weight and constructed to run on the Commodore 64’s 6502-compatible MOS 6510 processor. The NES’s Ricoh 2A03 processor can be largely 6502-compatible, so DeCrAzYo concluded it might most likely work.

However the NES solely has 2KB of RAM (plus one other 2KB of VRAM), whereas the Commodore 64 has a beneficiant 64KB. The Commodore 64 additionally has the power to learn from disks.

Each of these points have been solvable through the use of a Japanese Famicom as a substitute of a North American NES. The Famicom had upgrades accessible so as to add a further 32KB of RAM and a rudimentary disk system. There may be additionally a keyboard for the Famicom, which makes navigating a Unix shell a lot simpler.

By using the Famicom’s upgraded reminiscence and disk system, DeCrAzYo was in a position to modify LUnix to load applications from disk as mandatory. DeCrAzYo additionally needed to change the way in which the Famicom’s disk system works, as a result of it may usually solely learn information sequentially. With these modifications, LUnix boots and the person is ready to work inside the shell.

In emulation, this labored nicely. However that was solely as a result of DeCrAzYo was in a position to crank up the run velocity by 100 instances. In actual life and on precise {hardware}, it is extremely sluggish. DeCrAzYo was in a position to check that on an NES utilizing an Everdrive flash cart. With no Famicom keyboard accessible to kind instructions, nevertheless, he simply bought a blinking cursor within the shell. However he did show that Linux Unix can run on an NES!
