Macintosh LC 550
Performa 550/560
All-in-Ones1994Uncommon
The LC 550 replaced the 520 with a faster 33 MHz 68030 and 4MB of RAM standard. In 1993 and 1994, it was the all-in-one Mac in most elementary school classrooms — familiar, reliable, and capable enough to run Oregon Trail, ClarisWorks, and HyperCard simultaneously. Millions of children learned to type on machines exactly like this one.
