Sorry, I forgot about them.
I've never had any Amigas THAT new.
The story I heard was that it worked out cheaper for
CBM to get a bunch of
speed-switching floppy drives made up instead of modifying the disc controller
to support multiple data rates. I'm not sure I believe that...
It also provided a way to retrofit to machines that didn't support the
higher (1000bps) data transfer rate. The Weltek 180 RPM 5.25" drive
provided 1.2M support to XTs.
