I have a C64, 1541 and a PPI printer interface connected to a
Panasonic KXP1091.  After using the system for anywhere from 30 min.
to 1.5 hours, the video display goes flakey and the system hangs up. 
If I disconnect the PPI interface, everything is fine (except I can't
use my printer!).  My kids can play games for hours, but my wife can't
write her letters.  My kids have also noticed that the PPI interferes
with the loading of certain games (e.g. Castle Wolfenstein). 

Has anyone seen this behavior before?  Any suggestion on what might be
the problem and how it can be fixed?

Thanks!
