2.88MB, acording to the label on the eject button of my PS/2 Model 77 :)
I have about 10 of the disks that I got when work where throwing them 
out, I grabbed them as I could make use of them.

IIRC there is also a series of floppy controlers for the Sinclair QL 
that can format these disks to 3.2MB.
