Hi,

After coming back from a short vacation, I noticed that all of a sudden,
spurious characters were cropping up on my Z29 terminal.  When I type
something over them they have a tendency to do one of the following:
	- display the typed character in correct case
	- display the typed character in the wrong case
	- display the char whose ascii value is 15 less than that of the
	  typed character.
	- and so on...

Also, these occur randomly all over the screen, making it difficult to use
the terminal.  I believe that there is something wrong with some RAM 
that stores the characters that are being currently displayed.  Does anyone
have any ideas about fixing this ?

Thanks in advance,

Tamal Mukherjee
