Missing platform: Sharp X1
The Sharp X1, a Japanese system which pre-dates the Sharp X68000 is missing.
And “Fujitsu FM-7” is also missing. The FM-7 was followed by the FM Towns which is listed, but without the Fujitsu name.
Technically there was also the FM-8 and the FM-10. The FM-8 pre-dates the FM-7, and the FM-10 was targeted at business users only. I don’t think many games exist for the FM-8 and FM-10.
