Currently away from my A1200 so I haven't touched it in ~3yr.
I'm hoping to move my A1200 to my current location soon and install current versions. The A500+ and A600 I have with me do not have a capable (MMU) CPU.
The last time I had cli-only on Debian (couldn't get X to work), and had X on netbsd.
No GPU, just AGA. Any GPU would make X much easier AIUI.
