The world's slowest Linux PC

This reminds me of the dial-in server I built in our student home back in &#x27;97-&#x27;98. It was a 386sx 16Mhz with 2MB of memory and a 40MB hard drive that you had to preheat in the oven or it wouldn&#x27;t spin up. That was realistically the lowest spec&#x27;d hardware you could actually get to run linux on.<p>It took half an hour to boot, but that was okay since it was always on anyway. It took about 5 minutes to set up a ppp connection using a dial-in modem, and then the whole house had internet access through its network adapter. Unless someone had tripped over the coax cables again of course..

&quot;Calibrating delay loop... 58.77 BogoMIPS&quot;<p>As a comparison, from my i7-4771 @ 3.5GHz:<p>smpboot: Total of 8 processors activated (55999.93 BogoMIPS)<p>Computers sure are fast these days. Too bad we write such slow software for them.

How do you emulate a 32 bit CPU with only eight bits? Seems like you&#x27;d have to quadruple everything and then flatten it again after.

While I agree it is not novel at all [1] it is a useful exercise for someone to do and it especially reinforces the notion that Turing discussed with respect to computability. For a long time (and possibly even today) every IBM mainframe could emulate (at speed or faster) all previous versions of their mainframe line such that the investment in software was preserved.<p>[1] I did a PDP-11 emulator on the Arduino with FRAM chips for &#x27;core&#x27; which was made quite a bit easier by the existence of PDP-11 instruction set diagnostics, and other test software which validated the CPU was running &quot;correctly&quot;.

Somehow the fact that this was accomplished by emulating a 32 bit processor with an 8 bit processor, made this less appealing to me. I&#x27;m sure it was technically very challenging, but I would have been more excited to see Linux somehow running natively on the processor. I wonder what the slowest processors running Linux natively are?

How I would dread debugging this machine.

Interesting, but I found this effort <a href="http://www.homebrewcpu.com/" rel="nofollow">http:&#x2F;&#x2F;www.homebrewcpu.com&#x2F;</a> more impressive overall. It quite literally is a home made CPU which then had Minix 2 ported to it and booted. A very impressive achievement.
