Call it what you like, but it's basically a line-based "framebuffer" in memory, and the display just happens to be reading from that memory every time it draws

Call it what you like, but it's basically a line-based "framebuffer" in memory, and the display just happens to be reading from that memory every time it draws a line. IIRC you get something like 80 clock cycles to blit your pixels into that memory space before the next line gets drawn, but it's still acting as a framebuffer.
- faragon 16y agoNo, it is not even a line-based framebuffer. Starting on every H-Sync interrupt, the CPU has to change the TIA chip latches with accurate timming for "producing" pixel output. So, there is no framebuffer at all.
- nuclear_eclipse 16y agoAh, then perhaps I'm confusing it with another console that predates my existence :P
