So the Commodore 64 is kinda back [1]

They missed the huge opportunity to bring back the OG nerd fight by offering an Atari 800XL case as alternative ;)

I definitely was and still am in the Atari camp!1!!

@jwildeboer I am very happy to see that my first computer, the TI99/4A sees a bit of a renaissance. It was a cool system - once you had moved past it's crazy design quirks.
When I first wrote assembly for a 6502 (a Commodore 4032), I had real difficulties wrapping my head around the fact that it could only deal with 8 bits at a time.

@pjakobs And I loved the Atari 800XL because the ANTIC chip could do split screen where you could change the resolution midscreen and have separate viewports.

@jwildeboer ah, yes, I had to wait for the Amiga for that.

@pjakobs Both Atari 800 and Amiga had the same chip designer, Jay Miner ;)

@jwildeboer Nice to having had that in hardware. For David Braben's Elite on the Acorn B they had to sync mode switching to vertical blank timing to get the higher monochrome resolution in the upper part of the screen and the four colour „cockpit" at the bottom.

@musenhain The whole ANTIC/DLI concept was quite advanced for the time, in my opinion. https://playermissile.com/dli_tutorial/

@jwildeboer clearly on the way to Amiga's Copper but iirc, Copper could write to all registers of the chipset. @musenhain

@pjakobs Sure, but ANTIC being designed in 1977-78 makes it quite special :) @musenhain

@jwildeboer @pjakobs Atari 800 had innovative Atari SIO bus designed by Joe Decuir, who later on took the same basic design, and created USB ;-)

@jarkko Yep, handled by the POKEY chip. Together with ANTIC and CTIA/GTIA the Atari 800 series was full of innovation :) @pjakobs

@jwildeboer @pjakobs not to mention that everyone had Atari joystick ports in the 80s and early 90s :-)
