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.
I seem to spend half my life logging into thing's, confirming 2fa,confirming biometric data. Then when I go back to the first thing it's timed out and I have to sign in again.
I started something similar but for Sydney with the ultimate goal of being an agent simulator, simulating everyone going to work etc. Project got a bit unwieldy and is on hold while I mull it's future over.
There are still BBS you can access via telnet (and actual dial up if you really want), after the fifth one asks you for your full name, street address and phone Humber it gets a little old.
That gives you a standard OFS bootblock that returns to AmigaDOS. Mine is a custom bootblock, same DOS\0 magic and checksum format so Kickstart accepts it, but it never enters AmigaDOS.

Fair, I should have been more specific. The network driver is the popular cnet.device which is compatible with my PCMCIA ethernet card. It's loaded from fixed floppy sectors.

Agreed, and I don't. It's a multi-stage boot that stays at exec level throughout, AmigaDOS is never started, no process is created, no startup-sequence runs, _DOSBase is explicitly NULL.
The disk is a standard 880K ADF with no filesystem at all, it's just raw binaries at fixed sector offsets. The only ROM libraries used are exec.library, intuition.library and graphics.library for a debug display. Everything else is self-contained on the disk.
So you're right that it isn't the bootblock doing the networking.
I used cursor with a mix of Gemini 3.1 and opus 4.6.
It referenced the Amiga ROM Kernel Reference Manual, appendix C to create a boot block in assembly. It's a raw sector-mapped image, the build process creates a blank adf, which then writes everything at it's fixed offsets and we go back with another tool to patch the bootblock with the right checksum so the kernel accepts it.
I copied that adf to the A1200 so I can then write it to a real floppy.
There's definitely been success in using generative AI for vintage Computers. Just the other day I got it to produce a bootable floppy for my Amiga 1200. It loads the network driver, uses BOOTP to get an ip address, connects to a server and then downloads code via UDP that it will then execute. I doubt you'll get it doing amazing graphical scenes like you see in the demo scene though.
I've never had great luck getting iodine running anywhere. The one and only success I've had was on an aircraft where, after numerous attempts at different things, the best I could do is connect to an SMTP server and send an email manually.
