[R-390] Incomplete IF module

[Les Locklear]

Lots of those surfaced in the late 80's. In fact, many were marked with an EAC spare 
parts contract number. Clavier (who was originally Capehart then finally Fowler) made 
some of them also. Tom Marcotte has the list. I'm at work and don't have that list 
available.
