The video circuitry of the LC575 logic board requires two VRAM SIMMs of identical size. MicroMac can provide a pair of 256KB VRAMs to display 8-bit color or a pair of 512KB to display thousands of colors. Or you can utilize one VRAM SIMM that you may have installed in your 68030-based Mac and pair it with a second, identical VRAM SIMM.

For example, if you have a 256KB VRAM SIMM installed in your Color Classic computer, you must get a second 256KB VRAM SIMM in order to get correct video output from the LC575.

Upgrade Installation: Prior to installing the MicroMac 68040 LC575 Logic Board Trade-up you will need to update or reinstall the System software so that it is compatible with the LC575. This is a simple procedure that is outlined in the documentation that comes with the LC575 upgrade. Once you have the correct System software installed, the installation involves removing the current 68030 logic board from your computer and installing the LC575 logic board.
