Yes, I have a SGI Indigo2 with NetScape FastTrack with server-side JavaScript running in my basement! But it is not the same as Node though. ;-)
I am selling it btw! Look at the CRT-screenshots. :-) https://www.kleinanzeigen.de/s-anzeige/sgi-indigo-2-mit-nets...
Oh man, it is really cool, hope it gets a nice new owner.
