I don't think they ever developed the Tower series, or related OS to run
with Intel CPUs. Unisys also released machines using the same hardware,
but with different model numbers.

I have a Tower 750 (I can't remember the NCR 'official' model numbel for
this), with a couple of 380MB Maxtor SCSI disks in it, 150MB SCSI tape
drive, 16 terminal ports ( I don't have any breakout boxes
unfortunately), 10Mbps ethernet, 39MB memory (that's 32MB of
user-accessible memory, 7MB of ECC / parity code - those memory boards
should keep running forever :)

I've got X-Windows (release 4 I think it was) for the machine - they
appear to be pretty quick boxes from what I remember (due to no free
space I haven't used the thing in the last two years - it failed to
power up last time I tried, so I need to do some work on it sometime)

Get hold of ethernet cards if you can, apparently they aren't that
common. Also SCSI controllers - I get the impression that MFM boards
were used most of the time rather than SCSI, it being a more expensive
technology back then. I'm missing the one most valuable resource for my
Tower - the OS tapes!

Any questions, just ask - I may be able to help, and should have a few
bits of info lying around for these beasts...
