9100 display annotation plate backlit?



#2

I don't own a 9100 (to my most sincere regrets), so I have to find the answer to my curiosity here: In pictures of the 9100, it often seems to me that the plate right to the display with the lettering "x-keyboard, y -accumulator, z-temporary" is backlit. Is this true or just due to the photographs? I have a 9810 with the same lettering, and it's definitely not backlit.

Just for curiosity -

Andreas
(and if yes, what about the model B, would be the next question)


#3

The annotations are indeed backlit, on both the 9100A and 9100B.

#4

There are two small 2-pin 15V incandescent bulbs stuck into a plastic housing behind the display panel. These bulbs tend to have the bases break off or the part of the plastic housing that they stick into likes to crack.


#5

Also, the silk screened display legend tends to wear and flake off.
