Note that Motorola also did the m88k which was their RISC approach. It generated a bit of interest, but was never successful. https://en.wikipedia.org/wiki/Motorola_88000

The Motorola Series 900 machines were interesting - I had one under my desk at work for quite a while. They had stackable units, including one that contained a SCSI 3.5" floppy drive that was way faster than regular ones. We also had a DG unit with the m88k.
