Repairing original Renault Clio Clock

This is clock from my parents car. Original IC is broken down. Back side I replace this IC by ATtiny25 soldered on copper side. Now we need 5V so I used 7805 IC XTAL inputs fits to original crystal
RESET pin must be disconnected Coil is drived by swapping LOW-HIGH STATE on PB0 and PB2. 5V is enough. Just reassembly :)
