Audiomedia III Card with Macintosh Systems
Known Incompatibility with older Audiomedia III Cards & The Blue & White G3 and G4:
A revision "QC" or later of the AMCC chip is required for Blue & White G3 and G4 compatibility. This revision number appears on the AMCC chip following number "5933". Older versions can cause your computer to hang while booting, or when launching Pro Tools or DigiTest. This chip was revised to QC on the Audiomedia III to allow for compatibility with PCs that did not allow you to disable PCI Burst Mode (it was revied shortly thereafter to QE). Ways to identify these boards are in the grid below:
| Board | S/N's Below | Manufactured Before | Board Rev Before |
| Audiomedia III | BK16376 | 3/18/97 | Rev E |
If a customer has previously updated their board (or received a refurbished card), the serial number will remain the same, but the board revision will be updated (and the AMCC chip will have "QC" or later). Cards with the revision "Q" chip can be upgraded. Please contact your local Digidesign office using the following procedure:
