Looking at Ebay it seems old RS/6000 have become expensive...
A Working 7012-390 is certainly rare, they were finicky beasts. I have a
7012-3AT (very similar to the 390) and it's failing diag in weird ways.
I've seen a few 390/3AT/3BT/3CT and all of them had similar issues.
If you just want a nice machine to run old AIX, try to find a 7011-250 or
any of the 7012 series (especially the later ones like 360/370/380). If it
doesn't have to be AIX 3.x, get a 7043-43P or 7046-B50.

Hi there!
I don't usually see much discussion on old IBM boxes, but I was looking
for a reasonably-powerful RS/6000 that can run AIX 4.1 and maybe 3.2.5, can
accommodate some decent disks, and isn't 200lbs. The 7012-390 looks
perfect, but I found this one on eBay:

Are 7012-390's really worth $3,000? Anyone out there have one they'd
like to unload for less than 3 grand? :P
Thanks!
