Does any one have the schematics for the IFB20
I have modified my ifb20 it now has a 15pin female connector to fit a HD fury directly to it
Now I am looking for the schematics to try and supply the 5v to the HD Fury from the IFB board

You don't need schematics if you know what parts are on it 
The blue line on the left points to a 5V regulator, the most right pin is 5V dc and the middle one is 0V 
To verifiy this I checked that the 5V is connected to pin 16 of the SN75175 and 0V to pin 8.
Sn75xx IC's (TTL) always have 5V dc power.
