Booting an IBM MP 3000 S/390 System

2015-08-04 Thread Guy Sotomayor
I spent some time today and made a video of my MP 3000 system booting up to z/OS. The video is here: http://youtu.be/WnJmeQR0GQU. Even though the video is about 9-1/2 minutes long, it takes longer than that to boot. I edited out some of the more boring bits. ;-) TTFN - Guy
