Hello everyone, I have a hardware problem. I have an Amiga 2000, Microbotics Hardframe with 40MB Quantum drive, Microbotics 8-up with 2 meg and an A2088 Bridgeboard (revision 3). The memory expansion and the bridgeboard don't seem to work with each other. If everything is installed, I get GURU's OR after a warm reboot OR after a few hours of working. If I remove the bridgeboard, the problem doesn't occur. If I remove the memory expansion, the problem doesn't occur also. Is there anybody who has the same problem or does someone know what the problem might be? I have bought a second bridgeboard (revision 4) but still the same. I tried several times the offical Microbotics test-program to test the memory expansion but everything seems allright! Please e-mail me if you have any suggestions! -- Marcel Knol, Vrije Universiteit Amsterdam, Department of mathematics and computer science, The Netherlands.

General hint, if you get problems on an Amiga with a bridgeboard: If the problems are really weird, everytime different, THEN pull out the bridgeboard, press EVERY chip tight into it's socket, check that all chip pins are aligned with the socket contacts, and finally put the bridgeboard back into the Amiga tightly. There seem to exist some sockets of mediocre quality. On my machine, this procedure has to be done every half year... Now the different point in your story is that you had the same with a second bridgeboard. Perhaps one of your other cards is not autoconfiguring and collides with the address space of the bridgeboard? (Bad, bad practice of some hardware designers, but really existing.) -- Best regards, Dr. Peter Kittel // E-Mail to Commodore Frankfurt, Germany \X/ rutgers!cbmvax!cbmger!peterk
