IBM 4331 Mainframe

[Curious Marc]

Let me know what you come up with for the 3 phase converter solution. I have the exact same problem right now to provide power for my 3 3420 tapes and the 3803 controller. Also have 220V 50A single phase coming in the shop (er, garage), courtesy of the EV charger.

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.

Starting to power it up will probably be a while yet.  ;-)
