You can't use a PC floppy drive directly in the P2000 you can modify the floppy to be in Drive select 0 mode ( PC floppy are in drive select 1 mode ) You have to find the jumper or to desolder DS1 jumper and solder DS0 jumper in the floppy drive.
The other solution is to make a flat cable with a twist ( I have done that in my P2000 but I have to verify the exact wire I have twist ).
