=== EGA ===
Could display the CGA modes, and an extended CGA mode at 320x200x16 colours, the 16 colours being only the CGA full palette, this is probably the detail which killed the EGA. Otherwise it had its native colour mode of 640x350x16 the palette being set from the 64colours EGA palette (2x2x2 bits), such mode was actually even better than what an Atari ST could do... despite a lesser total palette to choose from, the same amount of colours (16 with no trick) were displayed at a far better resolution too. This 'Real EGA" mode was rarely well exploited for obscure reasons by game developers who wanted to keep a retro-compatibility with CGA versionsand graphic portability with other 320x200 resolution computers.
