 Bigger Bigger  Smaller Smaller  Reset Reset

HI everybody, i found this older ceiling projection clock part the other day and was wondering how i could interface it with my arduino. there is an IC under a glob of epoxy im almost sure, 8 pads for connections on the board only 7 being used, 2 for powering a red LED. The 5 wire ribbon cable must contain at least 1 power and 1 GND, meaning it uses 3 wire communication? Im not really sure. it uses the red LED behind and older style LCD That projects up to 4 digits with a colon in the middle. Any ideas on how to use it? heres a link to some pictures.

Is it still hooked up to the rest of the clock?

Do you have access to a logic analyzer or even just an oscilloscope?
