Hi,
I got a Neptune and a Sirius with a Pegasus2 ISA Card.
They only need to get the power from the AMiga Video RGB connector.
The RS232C port is there only for enhanced control, not for powering.
You must have a trusty PSU of 50/60W at least and a well working A600.
I successfully tested them on my expended A1000 !!!
Does your POWER LED turn on when you push the power button ?
Do you well have the special DB23 -> DB15 cable ? if not ... :rtfm:
