Was the Amiga memory map posted to this list? I sent a message to Ralph asking about how the 53c770 chip accesses the Amigas memory and he gave a rather short answer saying it can DMA to all the Amigas memory using big endian '040 bus protocol. I'm sure that is a complete answer that tells me all I need to know. Does that mean the chips sees the Amiga in a flat linear memory space. i.e. can see all chip/custom chip and fast ram and would access it just like a 68040 chip. i.e. the locations would be the same numerically. Another i.e. if a custom chip or memory location were at $DDXYWZ00 to the 68040 if would appear the same to the SCSI chip? If anyone can point me to a message or FAQ that describes the Amigas memory layout relative to the processor I would appreciate it. Fred |
