I don't know where you got this misinformation from, but Power Macs do support
800K floppies (apart from recent models which don't have a floppy drive and
perhaps the G3 models).

Every Mac previous to the Power Macs also supports 800K floppies (apart from
the very earliest ones which only had 400K drives).

See the "Power Macintosh 7600 Series: Technical Specifications" at

Other Technical Specifications documents on the TIL site for other Power Mac
series computers also contain this text:

* Internal Apple SuperDrive floppy disk drive
-- Accepts high-density 1.4MB disks and 800K disks
-- Reads, writes, and formats Macintosh, Windows, MS-DOS, OS/2, and ProDOS

Also see
This has a brief explanation on why access to 800K floppies is slower under
newer Mac models.
