LC 520
a.k.a. Performa 520
The LC 520 and Performa 520 are twins. They have 4 MB soldered on the motherboard and a single SIMM socket for memory expansion. Like other 500-series Macs, it has a slide-out motherboard.
With the ports on the motherboard facing you, you will see a SIMM socket on the far left. This can be filled with a 1 MB, 2 MB, 4 MB, 8 MB, 16 MB, or 32 MB SIMM. The 72-pin SIMM must be 80ns or faster.
To add memory, simply put the new SIMM in the RAM socket.
VRAM
The 520 ships with 512 KB of VRAM on the motherboard. You can expand this to 768KB by installing a 256 KB VRAM SIMM in the socket to the right of the memory socket. Some configurations may ship with 768KB.
