The splitter is an ADB power tap, it looks like. Those were used by certain devices for power, but are also handy for those of us looking to wire Ethernet or WiFi boxes to our classic lappies. I'd certainly like a whack at that.

theos911, if you have something of the right gender to connect a mini-DIN PhoneNet to DB-9, I'd be grateful. I have to check the gender on the FastPath (not at home right now), but I am pretty sure it is female, so it would be female mini-DIN to male DB-9. I will verify later. Let me know.
