Alternatively, you can download a trimmed-down DVD ISO image of Slackware-current.
I maintain a 2 GB ISO image here:
http://taper.alienbase.nl/mirrors/sl...e-current-iso/ which is being created by the same mirror-slackware-current.sh script which was mentioned by onebuck.
The ISO images are automatically re-generated within a day if there is an update to the ChangeLog.txt . You can be fairly certain that you are downloading the most recent stuff.
I can keep the size of this ISO image below 2 GB because I do not add the source tarballs to the image file.
I also have an ISO of 64-bit Slackware-current... I assume that you are able to guess the URL.
