That's like the opposite of what Amiga did to add 2MB (raw) high-density
floppy support to all models - since it wasn't feasible to get the
installed userbase to upgrade their Paula chips, even if C= wanted to
make a new one, they went the other way - the drive spins at half-speed
when high-density media are inserted so that even a 1985 Paula can
keep up with the bitstream.
