I have a parallel port MicroSolutions 2.8M drive.
Sorry, but I intend to keep it.

In addition, some models of Next computers had them (called "4M" for their
UNformatted capacity).


BTW, in order to call it "2.88M", you would need to use3 the IBM drive
de3finition of "megabyte" of 1024000.  If you define a Megabyte
("Mebibyte") as 1048576, then "1.44M" has 1.40625 M, and "2.88M"
has 2.8125 M.
