karstens grinding machine with eckelmann cnc86 controller program transfer.

dear friends.

we got an old karstens grinding machine with eckelmann cnc 86 controller.
there is no user programs and sub programs inside the controller but we have in floppy in ascii format.

is someone know how to transfer these to the controller?
what kind of cable do we need..?
do we need any special software for transfer...?

thanks in advance for all help.
