I grew up in the era of personal computers lacking any kind of protected mode or multitasking, and I remember how unreliable and frustrating these systems were, so I think it's hugely interesting that you're designing and implementing a proper user/kernel interface in an 8-bit system. Looking forward to seeing where the project goes.

Such a great amount of progress! It's a complex bit of work and you should be proud of what you've done so far. One thing that a good OS has built in is a good editor. One that it's easy to move around a file with some kind of debugging capabilities would be awesome. I kind of like coding directly to the device rather than having to hook it up to another system. I'm not sure if you could do it but an editor that has an optional hex mode would also be a fantastic feature.

I'm not one who can say this with authority (not being much of a gamer) but as I see it: nostalgic gamers just want nostalgic games on their nostalgic systems, that play the way (speed) they remember. And that's totally fair. But, they also remember the games their buddies played on the other systems that differed from the ones they had... I wonder if there's a way to relatively-easily (for those just barely willing to cut traces) add this Protected-mode system as an add-on to their existing systems; to be disabled/bypassed when playing their beloved games, but enabled when playing games from other systems? And then, maybe some folk might even begin designing games, etc. with that system in-mind, for the sake of sharing their work with folk who have other systems....
