possibli:
C451G = uPC451G = LM324
uPC451G (http://www.renesas.com/products/standard_ic/linear/opamp/device/UPC451G2.jsp) (web)
uPC451 datasheet (http://documentation.renesas.com/doc/DocumentServer/G17927EJ3V0DS00.pdf)

equivalent:
LM324 (http://www.ti.com/product/LM324) (web)
LM324 datasheet (http://www.ti.com/lit/ds/symlink/lm324.pdf)

NB: check the wiring, specally @vcc/vss to ensure the same pin-out
also, since this is an OpAmp, you may see input/'feedback'/output which may confirm the chip layout
----------

The 4066 is pretty obvious a logic chip... a "Quad Switch" to be more precise...
on your case, it should be Toshiba TC4066BF
here the data:
TC4066BF (http://toshiba.semicon-storage.com/info/lookup.jsp?pid=TC4066BF&lang=en) (web)
TC4066BF datasheet (http://toshiba.semicon-storage.com/info/docget.jsp?did=18812&prodName=TC4066BF)


solved by the help of the mighty google :D

sorry for bad english
