GV Teleport on a Duo?

I have a Global Villge Teleport Platinum 28.8 modem(Model A812) that I use on my desktop 7200/90.  I thought I’d also use it on my newly purchased (but old) Duo 280c (without an internal modem).  I don’t have a dock for my Duo, so it just has a serial port.

Now the problem:  The serial cable for the GV Teleport doesn’t fit into the serial port of the Duo.  This modem only has a single cable (no power cable) and presumably gets its power through the port.   The number of prongs is the same (8), but on the side with the 3 prongs there a a metal piece that prevents it from attaching.  This is different than a standard serail cable.

Is there any adapter I can use?  Is there another GV modem that I can buy that doesn’t have this kind of cable?  I like the fact that the GV modems are so compact.

Thanks for help in advance.

ComputerWare has a wonderful selection of cables which will allow just about any Mac to hook up to just about any peripheral.  I have found these folks to be wonderful when it comes to knowing which of my old machinery will magically work with a different cable (one containing two different connectors) and which will not.  They are very well versed in knowing what miracles you can and cannot work in terms of connectivity.

The answer to your question is simple.  The modem will not work.  Not only does it have that metal thing, but if you look carefully, you will note that there are actually NINE pins!  Three on top, four in the middle (This is where the extra one is), and two on the bottom.  You are correct in assuming that this modem draws power from the computer it is attached to, making it a very poor choice for portable use!  Only Geoport compatible 68k macs (660av and 840av) and PowerPC powered macs can run them.  Other GlobalVillage modems are available that are powered from the wall, use standard DIN8, and are still nice and compact.  For example, I checked out the Teleport 56, at www.globalvillage.com, and noticed that they say it runs with 68020 machines or better.  Thus, we can assume that it does not draw power from the computer.

I hope this answers your questions!
