Riscy Slack is a personal project for building Slackware Linux for my PowerISA based computers.
Website and file mirror can be found at:
Currently there is a functional install for Slackware64-current (Usually behind by a month or two, sorry)
I have been trying to get a build of Slackware-current installable for PowerPC 32-Bit Big Endian.
It has been slow, and not yet usable. The install ISO boots the new kernel, but the installer needs updating, it has trouble remembering there is a cd in the drive during install.
