4 floppy disk drives on a PC?

To be _really_ pedantic, both are 80 track disks.

The normal PC 360K disk is 40 _cylinders_ with 2 tracks per cylinder 
(double sided), 48tpi (should this strictly be 48 cpi?)

The RX50 is 80 _cylinders_, 1 track per cylinder (single sided), 96 tpi. 

It's the number of cylinders that matters.
