Diego from the SidecarTridge project realised a couple of tech demos, showcasing how a video stream generated on the respective Rapsberry Pi Pico is displayed on the Atari ST video output.ย 

Who is the master and who the slave here?

Those effects looks great๐Ÿ‘
This can be used as a kind of graphics accelerator for the ST then?

He also shows an Oric emulator running on sidecartridge:

Of course you're fully entitled to your own opinion but why not let people do what they absolutely love to do, even if you don't like it? There's nothing stupid or retarded about that.

Wasn't there a project with an ISA GFX card in the ROM-port some (many) years ago?

Really great idea, love it! :) What an innovative way to use our beloved Atari ST :)

I have mixed feelings, the performance is awesome but is a bit of cheating

Perhaps it's an unforgivable addition to demos or games, but what about GEM support? VDI on STeroids? 8)

You mean cheating in a way, like having more computing power on a GFX card than the main CPU?

Yes but also all the work is done by the ARM, the 68000 just copy the cartridge memory to the ST RAM so the shifter can display the frame buffer.

If you look at a shader demo, how much work is done by the CPU? Nothing.

Yes, I know but IMHO in a retro-computer the hardware should be "fixed", imagine that you add a second 68000 but a dual-core ARM... is a bit too much, although the performance and possibilities are amazing.

At the PC world it's harder to set a line, it's a constant evolution.
