THAT part is trivial.
What is a little harder is that a 2.8M drive (It is NOT 2.88 for anybody
who knows how to multiply) uses a data transfer rate of about 1 Meg bits
per second - twice that of the 1.4M. Although, in theory, it would be
"possible" to build a drive that spun at 150RPM to be able to use the
slower data transfer rate that 1.4M drives are accustomed to. (It was
done with 1.2M 5.25" in order to add high density to XT controllers!)
