Denial

As it turns out my tape drive isn't behaving, so I can't do much with them anyway...LOL, but thanks for the help anyway!

I have 2 tapes with (what I think are) games that I'm trying to figure out whether they work on a Commodore 64 or VIC-20. 3-D Man (the only other info on the tape says "nufekop") Coco 2, The Educational Computer Game (looks like it's made by) ISI Software Inc. 1982 Has anyone heard of them...
