OK - I had a 32/700 (it's parked at NMoC these days, but I expect it's just
too big and heavy to ever ship it to my place in the US), which looks like
the 32/600 in the far right of your photo. Biggest darn single PCB I've
ever seen in any machine, I think! 68030, 32MB RAM (not including ECC),
Ethernet, couple of 8-line terminal boards, SCSI, and 2 x 300MB disks.
I don't know how much commonality there would be between the two, although
it would seem good manufacturing sense to share parts and functionality as
much as possible.
Does your system show any signs of life at all? I *think* my system needed
the large internal battery connected (and vaguely-chargeable) before it
would fire up, even though that was supposedly only there as a memory
back-up during power-fail conditions.
I've also found some old emails which suggest that I had to replace a triac
and resistor near the AC input in my machine's PSU at some point (it's been
too long that I don't recall if the machine was DoA when I got it, or if
the PSU failed later)

The label says, Series: 3400 Model:2114 and nothing else. It's a large
skinny steel tower the a massive motherboard with a 68010 on it and uses
multibus boards for all the rest. I think it was called a 'NCR Tower XP' by
what I can find through google. It looks like the second from the right
here http://goo.gl/r3HTl I wish I could get that NCR tower running. If
anyone has any technical
information on Series 3400 boxes I'd love to know.
Hmm, what were the specs on a 3400? That sounds more like the re-branded
Unisys numbering; all the NCR Towers I was aware of had 3-digit model
numbers (unless by "NCR tower" you don't mean "NCR Tower" of
course :-)
