8' DSDD disk

Well, if you run Moore's Law backwards....  (I haven't done so, these
are totally off-the-cuff responses.)

Spindle RPM - maybe 30?

Drive size - eh.  9 by 12 by 1 (feet), maybe?

Spindle motor power - maybe .5 to 1 hp?  (ca. 400-750 watts)

Capacity - couple dozen kilobytes?

Hard sectored - had they even *invented* soft sectoring?  Maybe two or
four sectors per track?

Density - probably near the boundary between TPI and TPF :-)

Box of ten - you mean more than ten were made?

S-100 - goodness no, we don' need no newfangled high-speed interfaces!
