IIRC, at the time they came out, there was rumors to the effect that
the 2801 was originally going to be some higher numbered 1800 than the
others that did come out, but they slipped it into the 2800 line
instead as a lower feature model of the rest of the 2800's.

So, probably a different arch inside of the box than the rest of them.
