I use a 9pin plug on mine.  While its a different setup, I"ll quickly
explain the handle I came up with for pulling it. :)

I soldered a wire loop on each side of the plug so I can pull it loose.
Tieing a string to each ear on the casette plug will work, except for
C128Dcr users who would have to cut the ears off to plug it in.

Just a thought. :)
