README for iPaq H36xx Expansion Pack Pro-Engineer files and analysis.
=====================================================================

Please note from the 'MECHANICAL OVERVIEW' section of the Expansion Pack 
Specification:

All functional expansion packs must consist of four basic structures, including: 

(1) a uniquely-curved, injection-molded plastic BASE part which enables any 
expansion pack to physically slide up and onto the back of any main unit, 
[see Pro-E part file: jc_jacket.prt ],

(2) a common universal connector [see Pro-E part file: foxconn-fx3.prt], 
soldered to a PCB with absolute dimensions as to the position of the 
connector and as to the thickness of the board but with less criteria as to the 
board area dimensions,

(3) an unknown volume of 'new' electronics that will, at minimum, 
communicate through the PCB and the universal connector, and 

(4) a new injection-molded plastic top COVER part of specified shape at its 
bottom mating edge but of unspecified volume and shape (and, possibly, 
with unspecified openings) throughout its remainder.
[See example Pro-E file: jc_cover_pcmcia_final.prt]


Also, to assist the developer of new iPaq Expansion Packs, all Pro-E mechanical files 
for current PCMCIA and Compact Flash Expansion Packs (Jackets) have been made 
available as examples and for analysis. 

Please note the following instructions for various Pro-E Layers, Part files, Assemblies.
