It's a bit lacking in substance, but you're right, it is decent. At least
it doesn't make wild claims.

I was trying to think of some strange excuse that could make the phrase
"drum memory disk" meaningful. (Some UNIXes have a /dev/drum which is really
a disk; I also have an article from alt.folklore.computers which describes
one system's "firehose drum" which is really a disk, or maybe it's the other
way around.)

But I think the computer in question (made by Royal Precision -- is that the
same as Royal McBee?) really does have a drum.

The part I liked was this:

   A display case shows the progression of storage disks, starting with
   one from 1965 that's the size of a tractor-trailer tire. It held 2.5
   megabytes of data and had to be sandblasted to be erased.

Had to be sandblasted to be erased? Huh??
