Those Fish disks were a beloved nemesis of mine. When I was young and dumb I greedily collected a huge pile of them (I'm thinking like 1990, '91 or thereabouts) and then it hit me one day - if I'd tucked away the $3 per disk (or whatever it was) I'd have had the money to get an A3000! D'oh! Still, I had a lot of fun.
Rest in peace, Fred.
