RasterOps identified and corrected some problems with their 224/724 cards. The problems occurred on Macintosh computers with a 224/724 card and TokenTalk NB Card.
1. No video on the 224/724 card at powerup.
2. Selecting 24 bits/pixel on the 224/724 card causes pixels to change color under the cursor (and at random on the startup screen).
3. Zones and servers appear and disappear.
4. In all of the above cases, eventually a bus error (ID=1, sometimes ID=28) system bomb occurs.
The fixes are hardware rework. All finished goods and cards shipped since early May 1990 should contain this fix. Customers with problems should contact the RasterOps Technical Support department.
