I have a Power 7 machine that I can offer AIX and Linux VMs on (up to 8G of
RAM between the two, and 6 cores shared), and I'd be happy to offer root
creds to both. The machine itself has enough capacity that I'd be happy to
run CEC builders for everything on repo.hu. I also have a variety of old
equipment (Alpha, PA-RISC, Sparc, MIPS, VAX...) that's currently sitting
idle, and I'd be happy to repurpose those to run whatever type of build you
like, but they may not be fast enough for CEC, even for one project.

With server slices like that, the virtual processor you get from your <br>
