Keyboard on IIe is dead...

["J. Thaddeus Klopcic" <jtk@aws.com>]

My sister acquired 5 Apple IIe's for her nursery school which were
donated by a local elementary school.  My Dad and I pooled our
collective Apple knowledge to set up and test them.  I haven't touched
an Apple II for about 10 years or so, so we may be missing something
obvious, but anyway:

On three of the five, the keyboards fail to respond, except for the
Control-Reset and those funny little Apple keys.  We can get them to
boot an educational program that we have, but we can't get thr program
to respond, nor can we type in the Basic OS after hitting Control-Reset.

My first guess is that the keyboard interface IC has gone bad, perhaps
in an oscillator that drives the keyboard scan.  But, would this occur
in 60% of the systems?  We did have to swap around some floppy drives --
these guys all connect via a standard ribbon cable and header to a
dual-port card in slot 6.  Did we misconfigure the drive controller
somehow (I don't know how -- there are no switches or jumpers) and cause
a conflict with the keyboards?

I appreciate any advice.  Please EMail, as I obviously don't follow this
group too closely.  :^)
