TNC:
CPU
ROM
RAM
Modem Function

Never saw a TNC with a hard drive in it.

Your tunnel vision prevents you from communicating with the
rest of the group. Everything is about you, not the subject.

The term "equally useful" has no meaning. I can find an "equally useful"
substitute for my car, and that too means absolutely nothing.

different.
Nope, its a modern TNC substitute, cheap, with a color 800 x 600 display.
Better check your pulse Grandpa, something tells me it is way off...

Another jerk who gets off on pestering people with personal E-mail. His ISP
has been notified. Nothing worth bothering the list over.

Nope, you were being a smartass, whether that was your intention or not.
Ham IP addresses are as available as they ever were. We've got
lots of them. More than 48,000 have been allocated in more than
150 countries worldwide. There are over 600 gateway systems routing
disjoint blocks (subnets) of the AMPRNet via IPIP tunnelling on the
Internet.
All volunteer, all non-profit, all with no fees or dues involved.
Regional coordinators have blocks of addresses from which to hand
out to any ham who wants an address (or more than one, within
reason), and none of those blocks are fully allocated.
(In fact, I only coordinate the block allocations, and except for
here in San Diego, I don't assign host addresses at all.)
Just ask the dude who handles it in your area. See list below.
Take a look at www.ampr.org for a little more detail.

No problem at all, of course. My caution was to remind people NOT to
depend on the existing ham tcp/ip network in case of emergencies.
