logic could be in a CPLD or FPGA, leaving only the analog portion discrete.

At the speeds in question, I'm pretty sure the logic could be in a general-purpose microcontroller, too. But I'm not sure detailed schematics for the analog parts are available/open.

Still plain rva20/rv64gc+Zcsr, but even that is progress.

Previous India chips were missing c extension, and thus not able to run Debian and the like.

I am hopeful they will eventually catch up with rva23, the base the ecosystem has agreed upon for application processors.

According to the project website[0], it seems to not be open source. Too bad.

Not providing a DE9 atari controller port kills any interest on this which I might otherwise have.

>RTLinux or FreeRTOS are guaranteed-latency OS, that can reduce timing jitter.

Unlike seL4[0], neither OS has a guarantee of worst case latency.

RTLinux cannot realistically have one, as formal verification is not feasible due to its sheer size.

RTLinux had many variants, but in general nobody wants to introduce chaotic processes while running previously profiled runtime code.

It was odd xenomai was not as common as preemt_rt in projects. =3

Great debugging effort.

Now, with the complexity (MLoCs!) of the Linux kernel, this is definitely not the only bug to be found in there.

This is why Linux is just an interim kernel for these use cases in which we still cannot use seL4[0].

35 years of "interim" status. Is there a roadmap?

:-) LOL !

I'm not giving up my CRT.

Every home is required to have a telescreen.

Doesn't matter when the neighbor has a smart TV as well, tethering all the bad stuff to yours, whether you like it or not.
