I have a Quadra 650 that has a manual disk insertion drive. The front of 
the case is even formed like the later PowerMacs so I assume it is 
original equipment. And being a manual inject drive, it writes 800K 
disks that my IIc+ and IIGS can read in their 800K drives with no 
problems.

I seem to recall that the drives were the same between my Quadra 650 and 
my PowerMac 7500 (which can't write 800K reliably) so I assumed that it 
was something to do with the floppy controller Apple used on the 68K 
Macs vs the ones used on the PPC Macs.
