No, due to the risk of damage to the logic board or the card itself during the removal process, the VRAM Expansion Card or the AV Card must not be removed by the user. The computer should be serviced by an Apple authorized service technician only.
The Power Macintosh 7100/66 and Power Macintosh 8100/80 have the VRAM Expansion Card installed in the PDS connector, while the AV models have the AV card installed. In both cases, the card MUST remain installed to properly terminate the PDS bus.
Removal of the card or operating the computer with the PDS card removed can result in damage to the logic board of the Power Macintosh.
Installation of a NuBus card can be performed by the user, provided they follow the instructions for installation in the "Power Macintosh Getting Started" manual.
