@MMS: People thinking that not using the NMI line in Z80 cartridge for the C64 makes it slow are idiots. Even I, who don't really have any proper hardware knowledge, know that the very different system design philosophies of 65XX and Z80 systems cause the limited performance.

For the DMA, I think we are splitting hairs over words, but to me if the system, as in either TED of the CPU, has no direct control over what arbitrary data will be transferred to which arbitrary address in what arbitrary amount then it is not true DMA transfer. Given your definition, we may even surmise that watching let's say a party live stream over the Internet is a DMA transfer (over the Internet). But please point me out where I'm mistaken.
