Greetings! This I am writing to find more about my Macintosh LC 575. My knowledge is limited to; A: The business model of the 575 is called the Peforma 575. B: The location I received it from apparently had a huge stockpile of these things. They have probably thrown all of them away by now. (It was a school) And C: Some nitwit stuck a foreign object (such as a cookie or a piece of paper) in the built in FDD. It doesn't even let the disks enter because the drive moved. It also has a CD/DVD drive which works fine for media, but stutters with music. It also has a few games such as: Helicopter Lander, Factory, A clone of asteroids and some other games. It also has a few teaching and productivity applications such as a calendar, test score form creator, and a word processor. Once again, if anyone knows about any info about this system, please reply to this thread.
