Install Video Adapter Board Into Middle NuBus Slot
If you are reinstalling any NuBus cards, first install a NuBus card into the
NuBus slot closest to the power supply. Then, align the video adapter
board over the middle NuBus slot on the logic board with the inverted
AV or HPV card on the adapter board facing toward the power supply
(Figure 22). Verify the adapter board lines up with the inline NuBus
guides of the 8100’s case. Gently press down on the adapter board (not
directly on the AV or HPV card) until the adapter board is firmly seated in
the middle NuBus slot. If you encounter excessive resistance, check for
bent connector pins, re-align the adapter board over the middle NuBus
slot, and gently press down again. If you have a second NuBus card to
install, install it into the outer NuBus slot.

Support Note: IMPORTANT! – The video adapter board installs into
the middle NuBus slot since it aligns with the proper clearance in the
support framing of the computer's case. The video adapter board uses the
middle NuBus slot as a holder; it does not convert your AV or HPV card into a
NuBus card.
