Honestly not that far off from my 486 DX2/66 back in the day

We're talking about the equivalent of booting with init=/bin/sh, I don't remember kernel init on x86 ever being that slow

Oh yeah, well that may be. Once I got X working in Slack, I did boot into that, but then again, back then I didn't know how to recompile my kernel and the machine did this interesting loop where it would try a few different drivers until it got to the one that worked with my matsushita CD drive.

I think this is very impressive. I remember from eons ago people were running Linux on Amiga, but then it was the later models with 68040 processors with more RAM. As far as I remember no one ran it on a 68000 with 2 megabytes of RAM. Could Linux today run on an Amiga 500 with RAM expansion, in this same way?

The 68040 has a MMU, the original 68000 doesn't.

Linux can be built to not need a MMU, I have used that on Coldfire and Microblaze systems, I presume this Jaguar port is using it too.

On of the few things where getting Doom to run on it wouldn’t be that cool. But I love the post, except for the part where you reminded me I was old by acting like no one remembers that thing.

But… there was a commercial port of Doom to the Jaguar.

I've been slowly working on getting fuzix working on my amiga 1200. It boots the kernel I just don't have a file system for it yet. Though my 1200 has ~10MB RAM.

Do you only have a RAM expansion? If you have an MMU normal m68k linux will work for you. I have an a4000 running linux with an nvidia gpu ;) The drivers for the amiga filesystem etc all still work.

If you have the stock 020 we (me and the other people messing with this stuff) can make that work. the 68000 support needs one tiny thing, fixing the stack frame differences between the 000 and the 010+, and it'll boot on basically anything.

I already have patches to do it.

This is very cool. I thought literally no one else was using/interested in the 68000 support in the kernel. It was actually subtly broken for a long time. I think the fixes I did went in to 7.0 or 7.1.. I have some potential performance fixes for linuxmd like optimizing the multiplication that happens each time the kernel time infra needs to be updated. Would be cool to see if they help for you too and then get a "Te…

Hi! Thanks for all your work honestly, I saw the patches and most (If not all...) were necessary to boot the kernel. As for the mainline stuff: Sure! May I reach out to see how I can help?

I followed you on github. I think you should be able to see my email address? If not the one on the 68000 fix commits in the kernel works :)

Good luck finding a TT030 cheaper than a Falcon030...

I have one in here in good shape I'll sell you. Bonus if you're in Canada to simplify shipping or pickup.

I basically wrote them down as they came to my mind, but I agree. I'm still waiting to find a decently priced Falcon 030...

Back in the day my friends who did this ran NetBSD and not Atari's Unix, which was expensive and unsupported.

Actually interested if you're okay with shipping it across the sea.

“Modern Linux on the Atari Jaguar” is not a headline I expected. Thank you for making it real. Can it do 80 columns though?

Anytime! As for 80 columns... I'd probably need to choose a different (Narrower) font. With a bit smaller font I reckon it should be feasible to have it (Since current one has 8x8 glyphs).

Can the Jaguar push a higher horizontal resolution? Does it use graphics hardware similar to the Atari ST family?

If that doesn't work out, I'm in Ireland and also interested.
