only in pictures in ePay auctions.

Sadly, most of my "surplus" RS/6000s are MCA machines. The few PCI
machines I've got have uses. From what I've read, the P/390 is the
equivalent of a G2 S/390 on a board, with increased slowness. You
should upgrade to a real CMOS box like a 9672. :) I guess that G5
would qualify, but you should be able to get a G3 or G4 fairly cheaply.
I think I've seen 1 or 2 of them on eBay that were in the southern East

Ideas on how to get software... Also, ideas on how to configure them and
what hardware is needed besides the processor, DASD, and a boot device.
Like, is a 3270 controller necessary?
I was *supposed* to have DASD now, but (as I said in another email) the
EMC 5700 I had only had SCSI host adaptors in it, and no ESCON boards,
which to me seems quite retarded. According to EMC, you have to pay
for licensing to use a 5xxx for FC/SCSI, or to use a 3xxx for ESCON,
but not if you use the 5xxx for ESCON or the 3xxx for FC/SCSI. I have
no idea why they would have had a 5700 instead of a 3700, unless they
got screwed over by the sales rep and/or stupidity.
So, I'm back to looking for an ESCON PCI adaptor, or some other way of
bootstrapping it. I figure if nothing else I can get Linux booted with
NFS root to play around with. Not the best situation, but might end up
being useful for $business, as it doesn't incur license fees and it's
definitely the most stable hardware I own. I still want to come up
with a copy of OS/390 and VM/ESA + CMS to screw around with, and get
somewhat accustomed with JCL, et al.
It'd be really nice if Sridhar would un-disappear right about now, with
a copy of OS/390 or VM/ESA+CMS, but I wouldn't hold my breath for that.
