Changes
Those cheap IBM compatible PCs allowed the professionnal [[PC]] standard to enter many houses as a Home computer. The first and best known is the Amstrad PC1512 (and its upgraded version the PC1640).
* '''PC1512''' (1985) : the first model, what equipped with a custom CGA clone video card, enabling an interesting non standard 640x200x16 video mode.
* '''PC1640''' (1987) : second model, was an "upgraded" PC1512, sharing a lot of pieces. It had +128K Ram (640K) and was supplied with a an EGA video card and monitor. Hence it was more exepnsive an expensive and EGA standard failed to impose itself.
* '''PC2086''' : a PC with VGA display.
=== CGA ===
Enabled mostly 320x200 display with a palette of 4 colours choosen between 4 combinaisons combinations (only one colour to be choosenchosen) from 16 total colours. Could also get a text mode with character attribute based 16 colours display.
The Amstrad CPC can quite be considered a custom and more versatile CGA.
=== Amstrad's PC1512 custom CGA ===
Was mostly CGA compatible yet not ewactlyexactly. It could also get a special custom mode with a 640x200x16 display, the 16 colours being the CGA total palette, hence it could be as good as most badly exploited EGA cards.
=== 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 developpers developers who wanted to keep a retro-compatibility with CGA versionsand graphic portability with other 320x200 resolution computers.
=== VGA ===
This palette could have been great on an Amstrad CPC...
With high resolution like 640x200x16 or whole EGA 640x200x16 or 640x350x16, those Amstrad PC1512 or PC1640 could display better graphics on a color Screen than the only 16colours limited palette would indicate, but it wasn't very exploited and the CGAmstrad from Pc1512 could be on the slow side due to the huge amount of VRAM used for the special mode and being a PC-XT spec machine.
