OK, Ignore me. I just found it on my first try searching comp.sys.ncr
with google.
However, does anyone else still have one of these beasts lying around?
I'm probably going to need more assistance once I a serial console
connection to it up.

What I've managed to pick up looks like an NCR
Tower 400 series machine.
I managed to find a DA15 pinout for the majority of the serial ports on
the machine in the old classiccmp archive. However, the 'console' port
"B" is a DE9, not a DA15, and definately isn't the same pinout as IBM has
used.
Any help with the pinout would be appreaciated, thanks!

has a pair of MFM hard
drives (full height 5.25") a streaming tape drive, and a 5.25" floppy
drive mounted in it. Also has 8 RS-232 DA-15 serial ports, a parallel (?)
printer port, and some sort of other, possibly serial, DB-25 port.
It has a 68010 CPU, 4MB of RAM (As far as I can tell), and a multibus
interface that has the floppy/hard drive controller, RS-232 line
controller (with a dedicated 68010), a tape controller, and a controller
for a second bus that has an I/O modules of some sort stuck in it.
There's three more slots, so it's possible that additional Multibus cards
could be placed in it.
Right now (or after I get some sleep), I'm trying to determine the pinout
on the console ports so that I can connect something to the machine and
watch the console messages. I love (*cough* *cough*) the non-standard
DA15F and DE9F RS-232 ports on this thing.
The ST-506 interface drives are Hitachi DK511-5's, 41MB each. A bit
smaller than the 140MB drives I had with my Unisys U5000.
Pictures will come tomorrow, and be available at
