Thanks. There is also a similar one available from US Robotics, model
USR5637, for around the same retail cost. Either of these is also a
possibility, but I'm trying to not spend too much if I don't have to
as my friend's funds are limited.

But it's always good to hear about other peoples experiences with
these modems on a Mac. The one big question I always have is, if I buy
one of these, how well will it work?

Ah, eBay. Most of what I see available out there now are "Buy It Now"
listings, not auctions. I haven't seen a listing yet for the 3095 only
for the USR5637. These have been listed at either the same price as,
say, amazon or more likely at a higher total cost.

How they get folks to buy something from them for more money than it
costs to get it from amazon I have never figured out. And then there
is always this classic:  Buy It Now price: $5 Shipping $60. That one
seems to never grow old. But I digress.

Thanks again for the feedback on the Zoom 3095.

zoom makes a usb modem that is about the size of a pack of gum.  i
have used one with my macbook pro.

here's the description from amazon--zoom 3095 usb modem

on ebay, one of these might be cost-competitive with buying the
airport plus a power supply.

12V, hm. Maybe it's time Google up those sites which explain
how to morph a PC power supply to accomplish another task. I've
probably got some for an AT motherboard which are never ever going to
be used again for their original purpose.

Thanks, Bruce. Guess I'll go back to the eBay jungle and poke around some more.

That's what the label on mine says: 12VDC, 0.7A, center positive. Mine came 
with a 1.25A third party brick, so anything 12V above 700mA will work.

PSU specs for Apple Airport Snow White Dual Ethernet M8440?

2011-04-01 Thread iJohn
I've been looking for a USB modem that will work with the most recent
versions Mac OS X. I have a friend who currently uses the dial-up V.92
modem in her 800 MHz eMac for Internet access. I'm trying to plan
ahead if some day she moves to a Mac platform without a modem.

One suggestion was to not use a USB modem but instead go with one of
the earlier Airport base stations which included a modem.  So I
checked out what was available on eBay. Apparently it's common to sell
the Snow White Airport aka Dual Ethernet M8440 by itself and NOT
include the power supply unit.

>From pics I've seen, I think that the M8440 uses an external PSU which
supplies 12V DC and at least 0.7 A using a center positive connector.
Can anyone confirm any of that?

I have no idea what the size of the connector may be. Heck, I don't
even know how to TALK about the connector size for these adapters.

(I usually just use trial and error to try to close in on the right size plug.)
