|  Re: Is the Plus/4 more advanced then the 64?
I've seen the code for an FPGA blitter and an FPU... the size difference isn't even close! FPUs are huge. Though that is for a modern bitmap where color was encoded as the value written to screen memory instead of a separate memory location.
Remember, the C64 joystick? That has a blitter in it. At least the later versions do anyway. I believe it only works with the new 256 color mode, but it does have one. 256 color mode makes it easy since no logical operation with the destination memory has to take place.
*edit*
I forgot that a DAC has ANALOG circuitry, so that wouldn't be inside the TED, it would be external.
