A popular 8 bit computer from Commodore released in 1982.
The C64 community always over-exagerate the C64 sound chip capacities and it's marvelous graphical display, it's avant-gardist sprites and scrollings ability and it's pure awesomness.
But the facts are :
The SID sound like a chainsaw to the most delicate ears.
The Amstrad CPC is superior in pure graphism capability, thanks to a colorfull palette.
The Amstrad CPC was by far cheaper, fully equipped and with a fast Disk player (cpc 6128).
The Amstrad CPC range sold better in France.
And because so many games developped on the Amstrad CPC were puny Speccy ports which didn't really exploited the machine well, C64 games looked like superproductions.
By the way the C64 remains the best selling computer ever.
