I know for a fact that 90s era Liebert brand data center coolers used a 6809 based SCADA board. Presumably running microware OS-9. The business confusion at Hitachi was does management want us to innovate a hardware drop in replacement 2.0 for Liebert's coolers, or do they want us to just ship a second source for replacement parts for Liebert? Using Liebert solely as an example I'm aware of for actual customers. Speed doesn't really matter to Liebert as its not like data center cooler thermostats are going to be typed on 10x faster by caffeinated humans or fans will spin 10x faster. Although denser code DOES mean more marketable features could be added to the firmware. Of course if you compile for the more advanced 6309 then you no longer have a second source for hardware and theoretically Hitachi could screw you over by charging a lot more than motorola charges for 6809 processors once you're dev team is stuck on the 6309. All I can say for certain is in the end, if you open a 90s era Liebert you'll see a thermostat / early-SCADA PCB with a genuine motorola 6809 on it, so that was THEIR final decision. 90s era Saturn automatic transmissions had a similar issue and they shipped with genuine motorola 68hc11 chips. Again, its not like a 10x faster processor will decrease 0-60 times by ten times, so ... Generally Hitachi's business strategy WRT CPU licensing seems not to have worked?
