But so would a "normal" 1.2M drive run at a 1000K data transfer rate

I'm not convinced of that, Fred. Most drive read circuitry has some sort
of low-pass filtering and I suspect that it would get in the way of a 1Mbps
data rate. At least that's what I've found with some of the older 5.25"
drives.
It shouldn't be hard to hack a "regular" 1.2MB drive to spin at 180 rpm so
2.4MB could be formatted, but the media formulation is what I'm curious
about.
I should have said "For a short time, it was either very expensive or next
to impossible to get a 1.2MB-capable PC/AT compatible controller for a
5150". In any case, even the non-hardware-compatible CompatiCard I/II or
the Tall Tree setups were pretty expensive. I can remember hacking a cheap
Taiwanese XT controller to handle 500Kbps media was the most
cost-effective.
