TE Image Retention

From Ian Johnston <xxxxxx@mindspring.com>

Hey List,

All this TE talk prompted me to pull my TE out last night and play it for a 
while. Mind you, I haven't played it for quite some time, so perhaps that 
somehow relates to the problem I encountered. While playing I noticed that 
various images would remain slightly visible despite the fact that the 
images on screen were constantly changing.

This occurred when I was playing Alien Crush and then Air Zonk. I played 
Alien Crush for a while, popped it out, popped Air Zonk in, and then 
noticed that a ghost image of the Alien Crush playfield was faintly visible 
as I played Air Zonk. Said playfield was only really noticeable on a mostly 
black screen, but regardless I was a little taken aback.

What I'm wondering is, is this normal for a TE? I've taken great care of my 
TE since I've had it, so I can't believe that any kind of neglect on my 
part could've caused the aforementioned condition. Any input would be 
appreciated. Thanks!

Best,

-Ian
