I guess I'm at least 90% fine with the VDP inner workings. Where can I read now about the CPU? So far I only know what's written at the Motorola 68000 Wikipedia page, and of course I need to dig on.

Because it uses a 16 bit ALU to do arithmetic/logic computations. Hence the reason that byte and word ops take the same time, but long ops take more cycles, even when done register to register.
True, but I would say that the length in bits of the accumulator register (or any data register for processors lacking a designated accumulator) would be a good way to define it. For instance:
More than you personal view, is what everyone write on Internet, but that knowledge comes from selling. When a "new generation" comes marketing people have to convince millions of people, not necessary with any knowledge of computers and alike, to buy a new apparatus, while most of them already have a machine from previous generation. So the most obvious technique is to say this new one is "times better" than the older. For a period 8bits, 16bits, 32bits, 64bits... fitted perfectly.sverx wrote: ↑Fri Mar 09, 2018 12:12 pmsure, that was simply my opinion - the way I personally choose to categorize CPUs - surely not the revealed truth, I'm sorry if I ever given the impression that I'm here to teach, as I'm here to learn, not to teach (and beside that I think I haven't got anything particular to teach anyway)
