==Amstrad Custom chips==
The Amstrad CPC used one custom chip : the CRTC video [[Gate Array]] (or also called VGA ? don't remember well...but nothing to share with the Video PC standard...)
Latter [[CPC]] series included a "pre-ASIC"to merge the VGA and the CRTC.
The Amstrad [[Plus]] include a "second heart" simply referred as the ASIC.
The This Amstrad Plus ASIC perform many additionnal features that the old CPC series couldn't : the "Plus Features".
