HELP!! unknown components?
 

With regard to compaq tft450 mainboard,
P/N 00.54001.001. Rev:D
I am trying to locate the following components...9839w act14 14pin dil
designated U8 on board,and, ??77hh ??m75 cim5 8pin dil designated U47 on
board.
(I`m guessing this may be a LM75
As I am unable to locate a schematic for this
model I am not entirely sure of the function of these chips.
Can anyone help? either with a schematic or components.
Thank you.

Regards
Pete
