Since talking with Tom, we have found the problem with the C Ltd. board. It turned out not to be a PAL change as we originally suspected, but a strap to the DRAM controller that was incorrectly laid out. I apologize to anyone that has been frustrated by this problem, but realize that we were even more upset than you. The C Ltd. manufacturing line has been down for two-three weeks while we were solving this problem. When you are backlogged in excess of one-thousand units, it is difficult to shut down the manufacturing line. I am convinced that our problems have now been solved and that the C Ltd. aMEGA board is of the highest quality. As a side note,to anybody that wants to make the change quickly, and is handy with a soldering iron. There is a row of straps at the top center of the board next to a large cap. It is currently in the following state. O O O O O O O O O | | | | | | O O O O O O O O O | | | O O O O O O O O O ----------------- 1 2 3 4 5 6 7 8 9 Take a small drill bit or exacto knife and cut strap 5. Then solder a wire so that strap 5 is tied high. Your straps will now look like this: O O O O O O O O O | | | | | | | O O O O O O O O O | | O O O O O O O O O ----------------- 1 2 3 4 5 6 7 8 9 In the above configuration, the aMEGA board will run at NO, ZERO, NONE wait states. (Mandelbrots in 640 * 400 will be *Much* faster than Chip RAM). Since only 150 boards were shipped, I do not know how many people on the net are affected. If you are leary of using a soldering iron, and can be without your board for a few days, send me email and I will let you know how to get it updated. (Even if I have to do the update myself).
