I remember there was a 68000-series with a 56000 on chip. I would love to have seen a 68000 make it into the 64-bit era with a built in DSP. I did love programming those things. I would imagine some ColdFire-style pruning of the instruction set would have happened for the 64-bit era.


Are you sure you're not thinking of the Atari Falcon? It was a 68030-based machine that had a 56k as well. It's not on the same chip though.


No, there was one member of the 68K family (68456) that had the DSP on the chip.
