Very rambly video, pardon the excitement. I'm not entirely new to mainframes but this is the first time I get to play (and own) an IBM mainframe running IBM software. While the bigger machines that I saved (z9 and z10) need a warehouse, 3-phase power and a DASD, this S/390 has everything integrated in a "small" package. In this video I go over a brief overview of the machine, put it back together and perform a IPL!
Machine Type 7060-H50 from around 1999 and presumably used up until 2009
