Also the Dragon 32 & 64 (similar to Tandy's Color Computers), the Thompson series of home and school computers, and the Fujitsu FM-7, FM-8, and FM-77 series.
A number of the Fujitsu computers (with various CPUs) also had a 6809 for video, so some of the ones with a 6809 main CPU had two 6809s in total. The FM-7, FM-8, and FM-77 series all have two 6809s, the FM-11 EX has an 8088 CPU and a 6809 for video, the Micro 16S could have any of the Z80, 8086, 68000, 80286, or Z8000 CPUs and had a 6809 for video. I may have missed some models.
