The 680xx family was the best there ever was! Too bad that Intel blight was adopted for use in the PC.
I trained my students using 6800 and 8085 based trainers. About 2 years into my employment teaching the class, I wired up a 6809 CPU adapter board for the 6800 trainer and built an updated monitor ROM that had access to all of the 6809 features. It was a "one off", but I donated it to the department. The EPA68000 trainers became available in my last semester teaching. Too late to incorporate it into the course.
I still have my Atari 1040ST serial number 2. 68000 based. My TRS-80 Model 16 has a 68010 CPU board inside to run Xenix.
