You can run a bare metal Smalltalk-80 or Squeak on the Raspberry Pi.

I think Pharo uses the Squeak VM so it could conceivably run on the bare metal Pi as well.
I had a Xerox 1108 Lisp Machine from 1982 to about 1986 (did a successful commercial expert system product and used it for technical demos for marketing).
I think that Pharo is the closest thing today to that good old Lisp Machine feeling/experience. An amazing development environment.
Today, I pay for LispWorks Professional that while a great developer experience, is not like a Lisp Machine. I find it easy to get people to pay me to do Lisp development, but not Smalltalk.
Not sure if android or old nokias, or both.
They also add J2ME extensions for Symbian capabilities and N95 was the first handset to have real hardware acceleration to J2ME 3D features.
It was a big shock to everyone the communication to move beyond Java and C++ into C# and adopt WP7.
I find the whole idea of hardware that's specifically optimized for a totally different programming paradigm than what we're used to just fascinating. It's not hard to imagine why we haven't seen more of it: it's really expensive to iterate on a branch in the computing hardware tree, and you're probably better off just writing a runtime for mainline systems. But still, it's fun to think about.
I am a little surprised though that nobody's written an operating system like this for standard hardware. Still a big task, but an order of magnitude less ambitious than custom hardware and with many of the benefits people would've gotten from a Lisp machine.
