apt-get source toolchain-source and friends :-)

Although I'm still using a good lod .95.2 for kernels.

My A4000/40 also has 12+2. It works (slowly), but you do need swap ;-)

You need ZIPs for A3000. And the motherboard is still limited to 16 MB.

You can also try putting the ramdisk image on a spare partition using rawwrite
under AmigaOS.

IIRC he has an '060 board, which can accomodate the additional RAM.

Mine does survive apt-get update and upgrade, although I did remove everything
from testing and unstable from sources.list.

You can do this with Amiboot.

Many years ago (2.0.x-era?) I limited Fast RAM to 2 MB for a `quick' test, and
was able to boot, launch X, twm, and xterm ;-)

Debian installers are a different beast... I installed mine many years ago and
used Debian upgrade features to keep it current.
