Okay, so now I have to go into the basement, and re-read the serial
plate. NCR's numbering scheme is *not* intuitive.

I think that mostly applies to the '020 machines and higher. When I
first got my machine, I was told that it didn't really support
TCP/IP.

I'm pretty sure that's the case. The 68010 was kinda like the
80286-- some memory management was there, but it was considered
kinda brain-dead. The 68020 was the real breakthrough. Operating
systems for the 680x0 really took off after that.

That's about right. I have a complete set of spares in my closet.
The system board is *huge*.

Now you've got me worried. I really ought to take time to fire
up the thing.
