Thanks!!! It was definitly Dark Castle, now I'll lurk on a.b.e.m and see what shows up.

I wish I could remember more about the other game, it was like a triangle shaped ship, and it was kind of like a maze made out of big boxes and the playfield scrolled in all four directions and you gathered up crystals or something while eluding other ships, can't remember if your ship could fire or not...

Oh well, thanks again for the info though, I think we might even have a working mac classic lying around in storage where I work... :)
