IBM 4331 Mainframe 3 phase converter

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.

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. ;-) TTFN - Guy
