I am not sure I would call the VIC-II chip a > GPU but it was far more featureful than the Speccie's ULA. The VIC-II had sprites, could do soft scrolling, thus took load off the CPU. You would just set a new value for a register if the VIC-II to move an object. On a Sinclair Spectrum you would need to move a bunch of data around and redraw the screen by software. Not sure though if the term GPU I used applies for the VIC-II though. -- Andreas My random toughts and comments https://news-commentaries.blogspot.com/
