I noticed the above article while researching a problem for a friend. The symptoms described above are identical to what he is seeing. His A500 is quite old, this was confirmed when the dealer had to do some extra etch cuts etc. (procedure from Commodore) when the Fatter Agnus installed. The Supra and memory work on a friends (newer) A500. He called one of the local service depots and they said that they have seen the same problem and that there is no known fix. A call to Supra got the usual response - "We know of no problems". Has anyone else seen this? Is there any way to fix it? Any help is greatly appreciated.... Clint
