Most likely some kind of joystick interface considering where the solder joints are. Perhaps someone who's familar with the shematics can give you a more definite answer.
EDIT: Having taken a peek at the shematics releaved that it's 99.8% a joystick connector how Gods described.

I suppose it could be connected to the tape socket or something or possibly the 81 has an audio board fitted maybe ?
You probably will have to have a peek inside to see what its connected to :grin:
Spider's guess would be the most common thing.
I'll open it up and take some picks- Probably be Sunday
When the wifes out !!!
Would this look like this ?
