Re: USRobotics External Modem Power Supply

The only issue is finding out the required power input (AC or DC, voltage, polarity (almost always tip positive) and current required). "wall wart" power supplies are available very cheaply (usually under $5) from quite a few surplus stores, and in most cases the connector can be changed if necessary. But if the requirements are not marked, finding them can be difficult.

I'm fairly sure every external modem PSU I've seen is AC output.
I've seen USR ones at 9V and 18V.
