The real questions should be:
What speed does an 8 foot disk rotate at?
How big is the drive?
What is the power requirements for the spindle motor?
What is the capacity?
Were there any 8 foot hard sectored disks and how many sectors?
Were track density measured in TPI or TPF?
How much does a box of ten disks cost?
Is there an S100 interface?
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!
