Display Card 8■24 GC: Problems with PC 5.25 Drive Card (11/94)


I've been having problems with my Macintosh Display Card 8*24 GC with a PC 5.25 Drive card. I removed the Apple PC 5.25-inch Drive card from my Macintosh, re-accelerated the Macintosh Display Card 8*24 GC, and everything works fine.

The Apple PC 5.25 Drive sometimes clashes with the NuBus clock. This happens because the card has a 13-inch trace and six leads on that line. Symptoms of this issue include other installed NuBus cards not functioning properly. For example, NuBus video cards do not appear installed, and networking cards do not provide access to a network.

Putting the card in slot $E helps minimize the problem. If you experience a problem, try running with the PC 5.25 Drive card in slot $E.
