VRAM Considerations

upgrade VRAM SIMM to expand to 256 colors in 640 by 480 resolution
screen resolution does not affect color depth

The video circuitry of the LC550 Logic Board has 512KB base VRAM and can be expanded with one 256KB VRAM SIMM. MicroMac can provide a 256KB VRAM to display 16-bit color, or if your slower logic board already has expanded VRAM, you can transfer the VRAM SIMM to the new faster logic board.

Technical Hint:
You can identify the amount of VRAM of your current Mac by the following procedure:

  • Open the Monitors Control Panel
  • Check the possible (selectable) color depth choices.
  • Cross-reference the above table to find the amount of VRAM presently installed in your machine
