John Wiseman, G8BPQ has designed a stackable packet radio TNC that interfaces to a Raspberry Pi mini PC. This build should produce some very exciting and positive results for Packet Radio. He is also redesigning his famous BPQ node switch software to run under a Linux environment.
The Raspberry Pi is an ARM based mini PC that runs on the Linux operating system. It requires only 5 volts DC in order to operate. For more information about the Pi, join the Yahoo Users Group: Raspberry_Pi_4-Ham_RADIO. Several software builds are being developed for this PC for use with many ventures of Amateur Radio including IRLP, D-Star, Packet, APRS and much more. The mini PC is available for purchase through several websites for around $35.00 online. This unit boasts many features with a small carbon footprint!
The TNC is a separate board and does not currently have a list price. An integrated 1 watt 440 radio is also in development.
If you are interested in obtaining one of these TNC's, see illustrations of the TNC interfaced to an RPi and more information in the email listed below.
I am by no way affiliated with John Wiseman or the Raspberry Pi organization. The use of such technology can take us hams into the next digital realm!

I've been working on a TNC for the PI. It is based
on the TNC-X, shrunk to the same size as the PI, and with the RS232
interface replaced by a 26 way stackable header. The TNC communicates with the
PI via the i2c bus, which allows more than one to be connected to the
PI, or via the PI's async port. It can be used with any PI packet software
that supports a KISS TNC. For i2c, I've written a driver the converts from the
i2c protocol to standard KISS over a virtual serial (pty)
John Hansen W2FS, who produces the TNC-X, has agreed to
supply the PI version..It will be available both as a kit
and assembled and tested. It will take a few weeks to get boards made, but
it would be helpful to know roughly how many people are interesting in
purchasing it. If you are interested, please email me, off-list if you prefer.
those new to the group who haven't seen them, there are photos
