For the test, I simply hget'ed the kertex tarball. This is always
28kB/s... So even downloading 10MB takes more than 6 minutes.

For the version, i don't know: I downloaded the iso distrib from the=20
Bell Labs web site, some weeks ago, when the site was still online.

The problem is that I tried 3 versions of the distrib: USB and iso from
9atom (but the kernels panic'ed with my hardware); and the Bell Labs iso
(the kernel booted, but there were further problems with USB so I ended
up making the install "by hand", but with the files from the Bell Labs
iso).

Unfortunately see above: the 9atom kernels crashed for my hardware
(bicore Intel Pentium G3220).
