Re: Home Grown ActionTec Development Daughterboard

That would imply that I had an existing daughterboard.  The most access to one
of the real boards is the pictures that have been available on the list.  That
has actually made life a bit easier as I haven't had to worry about NDA
restrictions and such.  I actually went through all my junk electronics boxes
(and even some non junk ones) looking for the crystal last night.  I think I
could match just about any other "common" frequency but that one.
