Folks,
 Well in case any one has the slightest bit of interest, I have now plugged
 the RAID card back in and after replacing on of the drive carriers I can get
 five of the six drives to spin up. Its now copying stuff to my Buffalo NAS
 but as its 10Mbit LAN its not terribly fast. I think the NAS isn't very fast
 either. It looks like zipping up the files and FTPing the ZIP files might be
 the quickest way to go.

 I thought I had captioned that picture. It's the original RAID controller
 which I am not using. If I plug it in it starts the disks in the RAID array
 which takes ages, and steals the hard disk BIOS vector which I need for the
 SCSI card that's running the system.
 I didn't want to remove it fully as I need to label the cables feeding it.
 One feeds the top drive bays, and the other the bottom so if I ever need to
 put it back it I need to know which is which.
 If I get some free time I will have a go at starting the disks in it and
 repairing the RAID array, and perhaps copy the disks that are installed.

 I gotta ask, what's the deal with the dangling card?  That cracked me up!
 Thanks for posting some pics!

 card
  in it is 32gb so I can add 2 x 12gb drives or 1 x
24gb or some other mix. 
 The CD
  ROM sites on the same bus. I haven't tried
the tape drive yet..
  
 
 Well I found an XGA2 card in the pile of bits so now I have 1024x768 display
 resolution. I have swapped the CDROM for a SCSI DVD drive.
 I managed to boot MTS and there are a few pics here:-

 next job is to tidy up and re-assemble the case..

  Some time ago I acquired a PCI P/390 card (along
with the various LIC 
 files).  I
  went down the same path as you to build a P/390
system with OS/2 but I
 kept running into problems with OS/2 versions and supported hardware.
 I finally gave up and acquired a PCI based RS/6000 that I'll install AIX 
 on
and
  have an R/390.  ;-)  I haven't had the time
yet to make any progress on 
 it.
 But it's good to know that you've managed to do this if I decide to go 
back
  and attempt the PC route again.

I used Clonezilla to make an image of my PCI machien with a P/390E card
to a USB drive - but in your case that would, of course, require it to
recognize your RAID array (which it just might, if the BIOS recognizes it).
