Not quite. I believe it actually had a couple of advanced graphics modes that counted for gooseberry fool because most software didn't use it. It also wound up as the core hardware of the 464plus, I believe, but those graphics modes were not standard across all models.
You may be thinking of the c64gs, which is literally a c64 without a keyboard. Further mockery is earned for Commodore, because of the fact that the "normal" C64 had cartridge ports built in anyway, making the C64GS spectacuarly useless even within it's own useless niche in the big list of "computers that they tried to turn into consoles".
