So?
I can run (emulated) OS-8 (PDP-8) and soon RSX11M (PDP-11) on a Raspberry Pi.
A Model 3 runs OS-8 around twenty times as fast as the original.
Lots of other Obsolete kit can be run as well.
It is really nice that people are taking the time and effort and making old systems live again.
Intel X86 is not the only game in town these days.
{Waiting for the RPi to emulate Z/OS. Imagine a Beowolf cluster of them all running Z/OS!!!! IBM wouldn't like it though :) :) }
