Also worth trying would be the 1440k image, as that's the later standard 3.5" floppy format.

Open up an issue on GitHub and we can help you better. The usual reason for problems like this is the layout of the image is incorrect on GoTek, and/or the GoTek is set to the wrong CHS (cylinders/head/sector) for the image b

Is Alistair Riddoch still around? I've been wondering about him, his name is all over the early dev86 and ELKS C library code :)

We dropped all support for 286 or 386+ protected mode/paging etc, as well as produce only 8088/8086 instructions so it'll run on any x86 (including the PCjr with its peculiarities, remember that?) running in real mode only wi

Yes it runs on that Amstrad. A funny story about the Amstrad, at one point we added divide-by-zero trap handler in the kernel for user space apps. When the Amstrad reboots via our 'shutdown', its gets a div zero exception in its o

That's pretty cool about the radio stack! We don't support a compressed kernel anymore but have a way to compress user executables which saves about 30%. Sadly, even with straightforward decompression, that process on ancient 8088

Yes, one can actually boot and run a minimal system on 360k floppy, but if you want networking you need 720k. The native compiler might fit on 1440k but needs a lot more for any development if the C library header files etc are wanted.

There's a couple of ROM versions, one which runs with a ROM filesystem and boots a shell over serial and another which uses BIOS INT 13h calls for an external MINIX or FAT filesystem. Both are run using an emulator which allows selecti

Thanks for the comments! ELKS will run on an 8088, but also runs on any x86 PC using the legacy "real mode" which runs in 16-bit segmented architecture without an MMU or any hardware protection. It can be fun to boot a PC and see

Yes, they're available on the archived Dr Dobbs Journal DVD V6 ( https://archive.org/details/DDJDVD6 ), starting in the May 1991 section, or thereabouts.

Funnily enough, I just happened to have ported D-Flat to macOS and Linux in the last couple of weeks. Check it out (w/screenshots): https://github.com/ghaerr/dflat . It uses a small TUI library that maps multi-byte
