What a coincidence - this morning I started looking into what I'd need to get
into packet radio. There's a couple of hams here who'll help me out, I have
no license, equipment, or anything (except computers). What packet stuff do
you have available ? (reply via email, as I suspect this is OT)
On-topic, though, is that I wanted to use some of my vintage computing gear to
do packet radio (too bad I missed those c64 carts - that'd be a hoot!). I was
trying to think of what to do with an old machine that would be productive,
and packet radio popped in my head. I have an old Sun 3/80 or a Sparcstation
10 I could set up. Is there any packet software for old 68k macs (I have a
clean mac II that's begging to be used for something).

Nothing anymore, I purged it out at a local hamfest. Mostly it was
C64, PC, and Apple 2 based stuff.

Back in the day, I remember some VIC-20 stuff, too (since at the time
the C-64 was
running $400-$600, a bit too expensive to put in dedicated use, but
the VIC-20 was
under $100). If I had any part numbers, I'd give them; I just
remember folks with
VIC-20s and external TNCs at the Dayton Hamvention.
Essentially, stuff for the user port should be portable between the
two, like the
C= RS-232 cart. ROM cartridges, though, are entirely specific to each model
(totally different memory maps and physical connectors).

You need the license, to start with. Then a 2-meter (144-148 MHz) radio.
It's much easier if there's a data jack on it, like most mobile radios have
now a days. Packet radio only requires a few watts output, so a mobile
radio set on low power is more than enough. Then you need a TNC, a terminal
node controller, which is a modem for radio. The KPC-3 by Kantronics is by
far the most popular, though the KPC-3+ is better. Either should set you
back less than $100, maybe much less.
The TNC is setup and talked to over a serial link from... anything that
speaks serial. The TNC itself runs a BBS for messages, and you use the
device connected to the serial port for K-K stuff (keyboard to keyboard).
K-K is now known as instant messaging by another crowd.
Getting the license is trivial. You can download the current question pool
(with answers) from hundreds of places. Search for "technician exam
question pool" and find one that has the 2006 question pool. Better yet,
run down to Radio Shack and buy a copy of "Now You're Talking" which
explains the questions, the answers, and why each one is right (or wrong.)
With pictures, yet.
No morse code required.

I've never seen a US amateur radio license, but the UK one says that the
license is for 'self training in wireless telegraphy'. Now, I will
happily agree there's a lot more to wireless telegraphy than making
transmitters and receivers, but I am a little curious as to what 'self
training' you get by buying a transciever, buying a TNC, plugging them
together (and presumably use the standard 'rubber duck' aerial of the
portable transceiver). Oh, and running pre-written software to talk to
the TNC.
There's nothing wrong with buying equipment, but IMHO you really should
be thinking about doing some experimentation, modifications, and so on.
Actually, one reason I've never got into packet radio is a lack of
information one the internals of the TNC. I've not found an 'open' one --
as in published schematics and ROM source listings.

I'm pretty sure that the US one doesn't say anything like that.
Also, in the US, we're a bit farther along than using ham radio only for
sending morse code...

Well, there's a software-based packet radio module in the Linux kernel.
There's some details about it in the AX25-HOWTO:

Perhaps you could use that to figure it out. ;)

I'm not sure where that came from, but in the UK, you can end up with a
full HF transmitting license without ever doing Morse.

in the Linux kernel.
Sure, it's written in C, and if yoy think a non-progammer like me is
going to attempt to translate that into a microcontroller machine code,
you must be joking :-)

I do have the AX25 documents somewhere...
