probably not - you have two things going for you: 1. you were a minor at the time and 2. it was in the days before computers. my advice to test this out before going for a 'proper' job would be to join an employment agency where you need one carried out (i.e. a care company). you will soon find out what the score is, but i would advise you not to try and go digging yourself with any agency in case they make records of your requestsetc. good luck - it sounds like you have moved on from this spot of bother in your very distant past
