Hi to Crumar Users

Can anyone help? I have been given a Triogy alas it has a couple of 
chips missing. Does anyone know the chip  type numbers from a manual 
(or a Trilogy with it`s bonnet/hood up ) 

 IC 5 on board P876/2  ( left hand side of large middle board beside 
Power supply board - 8 pin i.c.)

 IC 10 on board P857/12 ( left hand side of right hand board behind 
keyboard - 16 pin i.c. - suspect its the TOS chip M083? )

I would be very grateful if anyone can provide the info
