Just to let folks know that I finally moved the IBM 4331 Mainframe this past weekend
from where it was currently stored to my shop. Pictures are here:

As can be seen in the pictures, it filled a 26? box truck that I had rented for this
purpose.
Right now I just have it placed somewhat in my shop. Some early tasks will be:
* I have to verify that I have everything. Even if I missed some items, they won?t be
scrapped. I just need to go over what is currently in my shop and verify that I
didn?t
leave anything behind. I?m mostly worried about cables at this point.
* I have to figure out some way to produce enough ?clean? 3-phase power to run the
peripherals (the CPU is 220v single phase) as I only have 220v single phase coming
into my shop.
What do they use 3-phase for? Motors? I remember disk drives with 3 phase motors. If
so, a VFD is a good low cost solution since those are specifically designed for driving
motors.
