Genesis Gottlieb, 1986

I'm working on a Gottlieb System 80B sound board for a Genesis. The sound effects work but the music does not. The LED on the board does not light up or blink, even if I hit the reset button. Roms are tested good on my other working Genesis sound board.

I've read about a System 80B sound board test rom by Marco Albus that will test the CPUs, ROM sockets, RAMs and input latches but I have not been able to find a copy of this test rom. Does anyone know where I can download this so I can burn a copy?

Let me know. Thanks!

You could ask Marcos himself... He is still active on this board. MarAlb

Hi,
I had some sound problems on my Genesis ( wrong sounds etc.) Turned out to be a connector problem (Gottlieb's connections aren't the best apparently ).

It’s not the connector as I have another sound board that works fine.
