huh. I guess there was a recent machine with sata and GbE and a
decent cpu/ram (tegra 2/1GB). $200. I'm still a little hesitant
about Nvidia, but to avoid further damaging relations with processor
designers I'll defer to Torvalds' statement on the matter from
Thursday in Finland.

Another neat comparison of 44 tiny devices:

I wonder which one will run Plan9 without much of a hassle. Have to wait somebody to crack RaspberryPi.

Hi,
I am waiting for my RaspPi to start some cracking, but meanwhile you can
have a look at http://kernelnomicon.org/ which is illustrating the
progress for RPi to boot FreeBSD. It provides useful bunch of info about
booting process that RPi uses - can be a very good starting point.

Actually I've toyed with the idea of a "Plan 9 from 8-bit space". It
would be a fun challenge, I think, and I'd be interested to find
exactly what compromises would be needed. It may even be less of a
challenge than writing drivers for the crap peripherals ARM SOCs always
seem to be burdened with, but what could you do with it when it was
done?

More to the point, you don't want any OS on an 8 bit machine.
A small driver library, maybe. But really, 8 bit machines today are
just for fun little micro-control projects and you really don't want
an OS in the way.
The first thing I did to make an arduino useful was reclaim the timer
thread that the arduino "OS" steals from you...

It's an 8-bit, what are you going to put on it, CP-M? ;) Granted, some
of the old 8-bit OSs can be quite nice. I really like the one in the
Atari 800, it has a really unified device interface, but it's no Plan 9.
Actually I've toyed with the idea of a "Plan 9 from 8-bit space". It

An overpriced and underpowered member of a class of devices that are
far short of running Plan 9 in the first place. And why on Earth is it
programmed in C++?

building block. Something like this:
- provide a tiny thread library
- provide 9p over USB|serial|UDP
- implement a simple 9p server framework & export a server
side interface where one can plug in sensor/actuator
specific routines and specify the FS layout via a string.
- implement a namespace convention for discovering
capabilities (for example a "help/" dir)
- it should be implementable as a verilog block some day!

What I am talking about is packaging up as a reusable
component. Specifically
- server side api
- ability to discover capabilities. no new client side drivers
for each new device.
As for "simpler than 9p" I had a different thing in mind from
what is in various iwp9 papers. Not worth talking about in the
abstract.

I'd like to share with everyone that I've just purchased one of these:
https://www.olimex.com/dev/imx233-olinuxino-micro.html
I liked how they have all their schematics and layouts are on github and
that the freescale chip would be a bit friendlier than something from
nvidia or broadcom (not to mention you can actually purchase low qty of
this chip if you wanted to). There is a larger version as well (go to
Olimex's main site and navigate to the product family 'olinuxino').
I've always had good experiences with Olimex stuff. I am really glad to
see them still in operation.
