Thanks Mfilos. I believe I'm going to leave this Amiga without subway by now. What I'm thinking is to put a Fast Ata MKIII, and it will put it's commands in the first line too. I will change them to 2º then. Can I have any problem adding the Fast Ata?
Don't tell me the ACA 1230/56 doesn't run AmigaAmp?
