All the Color Duos have thicker Lids than the original, Passive Matrix, 230/210 and the Later, Active Matrix Grayscale 250, hence, the Color Screen Upgrade Lids for the original Dock and the same lid on the Dock Plus. The 230/250 MoBos are the same, as is the 270c's, IIRC. I believe there was more VRAM aboard the 250 & 270c, but I'm a bit rusty on my PRE PPC Duo lore.
Save your 280c for a 2300 MoBo upgrade, they're made to work with ALL preceding Duos, their screens and HDDs! They HAD to be compatible, because Apple Promised a PPC upgrade path for the 5k$ Duos from Day ONE and would have had an enormous class action suit brought against them had they not delivered!
