Re: 3Com U.S. Robotics 56K Voice Faxmodem Pro power adapter help...
Thats weird. They said 1.5a instead of a voltage value, so 1.5 volts isn't in Amps.
The modem could easily use 12v though i wouldn't want to tell you to do this as it might damage it if i'm wrong.
I would step up slowly, as one of those have got to work as there are standard values. I doubt it would be 1.5v since this could be powered by an AA battery...
Hope this helps
