     This is untrue.  Both the 128k and the 512k Macs can deal with
800k drives.  They just cannot access HFS disks unless you use the
"HD20 Startup" file.  Both can even deal with 800k MFS disks.  How
do you get 800k MFS disks?  Why, format them on your 800k drive that
you have attached to your 128k Mac, of course.

     Don't buy a 400k drive, unless the price is way, way below the
cheapest mail-order 800k you can find.
