I talked to someone here on the net who was VERY nice about helping me out with the problem of HOW to ground the PAL Chips.! I did as he had done... but I was STILL having trouble... I called Supra and they told me a COMPLETLY different method to use... AND IT WORKED!!!! This is what they told me.... 1. Connect pin 10 (upper left pin when your looking at the daughter board while it is STILL in the Amiga> of all 4 PAL chips together... 2. then from your four chips with their pin 10's all connected together, go to the Electrolyticcapacitor about an inch or so away from the PAL's.... 3. From the Capacitor, go down to the mother board and connect to ground! I found a nice ground pad right by the power connector from the power supply, and soldered the wire right to the pad... Since I did this about 2 days ago I have not had ONE read/write error or ANY bit of strangeness from the hard drive. Including being told that a known program is not an object module... All of this has gone away since I did the above mentioned modification! - Doug - Doug_B_Erdely@Portal.Cup.Com
