Subject: IBM 4331 Mainframe
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. ;-)
Yes I remember having a gentle discussion with the University of Salford electricians, who
wanted to know why I wanted 2 x 100amp feeds for the room into which the 4361 (I think it
was a 4361, might have been a 4331 or 4341) was placed. I don't think we ever loaded
them at 100amps but that was what IBM required. One was for the AirCon and the other for
the CPU. If I remember properly those disks are the truculent ones. Assuming you have
AirCon they need to sit for several hours to acclimatise.
