Vintage Apple Macintosh LC575 motherboard 820-0464-A with full RAM
Tested and works great. Sound is loud and clear. RAM has been upgraded to 36MB (4MB onboard, 32MB SIMM), the maximum the motherboard can officially support. 512K (2x256KB SIMMs) of VRAM is installed allowing for up to 256 Colors at 640x480. The PDS and Comm Slot have been tested and function correctly as well.
The LC575 / Performa 575 was a popular machine when it debuted in the mid-1990s and continued to be popular long afterwards due to the motherboard being an easy upgrade for the Macintosh Color Classic. Commonly referred to as a “Mystic” upgrade, the 68LC040 CPU running at 33MHz (this motherboard has been upgraded to a full 68040 running at 33MHz) on a 32-bit bus was a noticeable improvement over the 68030 running at 16MHz on a 16-bit bus present in the Color Classic, with the higher RAM ceiling (36MB officially as compared to 10MB on the Color Classic) and additional expansion slots available making this an attractive upgrade option.
