Porting Sedoric to Jasmin (sedoric source code ?)

Before writing floppy support for LUnix, I'd like to limit the number of filesystems I have to support. As it seems Sedoric is the most widely used now, and it only supports microdisc while I only have a Jasmin2.
So I want to port sedoric to support the jasmin hardware. After looking into Sedoric 3.0 à nu it seems the hardware dependant part is relatively small. Also the book has the commented source code (full ?). But it would be simpler to have the original source files in build order. Are they available anywhere or do I need to extract the bins from floppy images and disassemble them by hand ?
What is the latest version, I think I saw a screenshot saying "3.6", was it a fake or something ??

I've written an info file for da65 (from cc65) to get a readable disasm of the kernel:

It seems the FDC is accessed only from XRWTS, so replacing it should be doable. Only the microdisc control reg is accessed elsewhere, but not much.
