I really loved programming it. The Z80 was nice and concise but quite restrictive, 68k really opened up with addressing modes and registers. I've had a quick scan through that page and recognise most of them from the dim distant past.
One thing I didn't see mentioned is it had a small instruction pipeline so we could squeeze better performance out of it by by careful instruction sequence. For example you wouldn't load a register and then use in in the next instruction because it wouldn't be ready and could stall. By what is effectively interleaving code where possible you could keep it running flat out. Every cycle matters!
