Wow! Is that Alan Cox programming on Dragon? This came faster than I dared to hope for. 2015 will be the year of the Dragon, again

- FUZIX on Dragon 32 + nx32 memory cartridge

This is FUZIX booting on real hardware
It can mount a root filesystem over DriveWire and execute userspace (init) from there. Unfortunately there is not much of userspace yet, except my little hand-crafted init greeting you all.
I am using a hacked-up version of my memory cartridge to have it running on my Dragon 32. There is also a patch for XRoar for emulating the cartridge. This FUZIX port is called "dragon-nx32", since the memory cartridge can have n times 32KB banks...
The original "dragon" port requires a Dragon 64 and replacing all ROMs. I also added DriveWire support to this one. Much of the code is shared between the two ports.

whoa, interesting stuff. Only a couple of days ago I managed to do a build of gcc-6809 so I may well try building this for my kit.

If you haven't heard much from me over the last weeks, it is because every spare cycle has gone into FUZIX hacking
Finally, I give you:
FUZIX running for real on a Dragon!

(note that SSH is simple shell and not secure shell)
The root disk is on the uDW, and the 128KB extra RAM on a "nx32" prototype cartridge.
All the code is at
https://github.com/EtchedPixels/FUZIX and the commit log shows what I have been busy with
A demo kit (including a patched XRoar for Linux) is at

That's really cool.
I sense a general purpose memory expansion cartridge is not far away
