  I have in front of me three modems. One is a Global Village TelePort 33.6
Speakerphone Fax/Modem. The power supply output:9V DC 600mA. The PS plug
looks somewhat like the ADB plug.
 The second Modem is a US Robotics Sportster Voice 28.8 V34 and 33.6
Faxmodem and the PS output: 20VAC 10VA. Plug is like most wall wart plugs.
Dimensions unknown?
 The third is a Diamond Supra Express 56k. PS output:DC 6V 500mA.
 The plug is similar to a audio plug in appearance, but smaller.
   My conclusion, well, I don't have one. Leave that to you.
