Purchased at a flea market on August 21, 2022. According to the date code, this unit was produced durring the 40th week of 1989 in Italy. There is some minor damage to the case, some chips in the plastic and stuff scratched into the back. Judging by external inspection alone, there seems to be a broken screw post inside, however I have not confirmed this as I see no need to take it apart and risk damaging it further, since it is functioning and was fairly clean when I purchased it.
