A month late to the IBM 100 years celebration party but I can at least contribute with some lovely experience exploring the #Power5 machines.

A few years before I got a job working with #AIX #UNIX Systems regularly (not any more) I got two #IBM System p5 505 complete with manuals and discs that I used as lab servers to explore the hardware management platform #VIOS, #AIX etc.

2x 1u machines with Dual Power5 1.65GHz, 36MB L3 Cache and 4GB RAM and UltraSCSI320.
