Does anyone have the schematics for a ProLog M980 PROM Programmer ? I am trying to read some 2732As from a Harris radio and the 'Overload' light keeps lighting on the PM9080 with or without an EPROM in the socket. I have the PM9080 prints and the problem looks like it's in the mainframe. The unit worked fine about 2 years ago when last used. Please reply off-list. Thanks, -John
