The machine continues to receive the hug of death .. especially with our friendly Europeans waking up. Have faith, it's still running. (And it's been surviving like this for four hours now.) I've turned down the logging level a little bit and turned off the beeper. On this machine, a 50ms beep on the motherboard buzzer is 50ms of delay. :)

I think it's impressive how your site's managed to stay online when many sites hosted on much more powerful hardware haven't been able to handle HN frontpage levels of traffic.

That keyboard there was a work of art. I can still remember typing on one as a kid. So responsive, so satisfying, it just compelled you to want to write more. I own a few mechanical keyboards now and none of them compare to the original IBM Model M (I have heard that there are companies making 'new ones' though so maybe I'll have to try one.)

Note that the original PCjr keyboard was notorious for being terrible. One of the major flaws that helped making that system a flop.

What were the other major flaws?

4.77Mhz on a V20? The whole point of the V20 was running 9.54Mhz.

There were several speeds of the V20, including the base version at 5Mhz. Using it as a drop-in replacement and keeping the system clock speed the same the NEC V20 would still give you a 15 to 20% performance bump because it used less clock cycles when executing many insgtructions.

(This machine has not been altered to speed the clock.)

Thanks ... I think people are having time-outs so it's not anywhere near close to perfect, but the machine has been running at 100% for five hours or so now and it is not crashing, so I'm happy.

Earlier quoted context omitted.

That is astonishing if water got on the motherboard

I had a 486 go through a tornado where the entire building was torn apart. Completely soaked. Brought it home, let it dry for a few weeks. Worked fine for a few years after as a mp3 player.

That must have been a beefy 486, as I remember I had trouble getting a Pentium 100 Mhz Toshiba laptop to play mp3's on Linux kernel ver 2.4, and it could only do so from the bash shell without XWindows running. It could manage it on Windows 98, though, but only with the windows media player, if I remember correctly. Winamp 2 was a bit of a CPU hog for some reason, even though I never used visualizations.

What OS signature do you get when you portscan it? :)
