I received a 1531 datassette (just after I FINALLY got that 26 games pack from Comtique... will post titles later if anybody's interested), and it's got a slight problem: the Play mechanism gets jammed. I suppose this is because it's bloody dirty, I opened it up and it's a bit grubbt, but if you push it back to its place, its OK.. so it surely needs a cleanup and proper lubrication.
