Re: Faulty Apple IIe

Hi Jeff,

There usually are others with more knowledge to answer questions like 
yours.  But no answer has propagated this far yet so I will try to help.  
A few years ago I had what I recall was an identical problem.  I solved 
it in just the way you suggested you might solve yours.  It took 
replacing one chip.  I think that that chip was the IOU.  As it happened 
I did not know which one to replace and replaced two or three before the 
mahine was right.

Try the IOU chip.  If that does not do it, try others--you'll find the
right (bad) one.
