Yes, it does. What I haven't figure out is how to concisely and accurately
convey the information without a picture.
Basically, the fingers are .080" across by .563", and spaced at 1/8". The
outside notches are .100+/-.01 inches. The narrow notches are .258", and
the wide notches are .510"
The short side notch and the shallow part of the notches are .625", the
deeper notching is .725". The deeper notching in the interior is .140"
(instead of the .100" on the outside edges).
The tabs are 2.240" wide. It looks like the center-center distance from the
first pad on a tab to the last is 2.125".
Hope that helps. (If you want I can just send you an Eagle CAD file for an
Omnibus card outline with edge connectors, and you can hack on it to make an
extended length hex card outline.)
