My apologies for losing this in my article database. On 15-May-92, Apple announced that they had identified a software bug in the 7.0 version of the GC Control Panel that ships with the 8*24 GC Video Card. Despite the fact that the video card provides accelerated graphics, it has to run with the 68040 caches disabled, a major pain for Quadra users. If you bought an 8*24 GC card for use with a Quadra or a VRAM Expansion Kit for your Quadra's 8*24 GC card, you can return the item for a cash refund from Apple through 30-Sep-92.
You don't have much time, but if you have a Federal Express number, Apple can FedEx you the forms, and you can FedEx everything back to them. They must receive everything by 30-Sep-92, which is why you must act fast. I'll bet Federal Express hates it when people use their name as a verb, just as Xerox hates it.
Contact Apple's fulfillment house at the number below between 8:00 AM and 5:00 PM Mountain Standard Time to request an 8*24 GC Video Card Refund Program Return Form. That form includes the instructions you'll need as well as packaging materials to return your card. You then pack up your card in their packaging materials (the offer is void if you use other packaging) along with copies of your invoices for your 8*24 GC Video Card and your Quadra (with the serial number clearly listed), the invoice for the VRAM Expansion Kit if you bought that, and the completed Return Form. Remember, time is of the essence!
