Build your own NeXT with a virtual machine
While it's neat to be able to run the actual OS, the title as provided from the blog is a bit misleading. Adafruit also did something similar a few days ago with Solaris.
I may be the only one as I see no one else has commented so, but when I read "build your own..." I'm thinking the actual hardware, or compatible. They should call these articles something like "Run XXX OS and software on your existing machine."
