Help! adapting a SCN2661in Grant Searle z80 design

[ali6x944]

So do I have to falsh the rom to operate the EPCI?
As the cpu have to adress them, I mean the programming pins /CE,A1,A0,/R,W

To use the EPCI with Grant Searle's ROM You will have to modify the source code in 'intmini.asm'. If you don't get it exactly right then it almost certainly won't work, so when you have built the circuit and written some code post it here for us to review.
