Title: Gorf Test Mode
Post by: rchadd on October 31, 2005, 12:48:07 pm

What happens when you reset the machine?

The test switch on a gorf is integrated into part of the audio amp.  A common reason behind test mode not working is having the wrong amp installed.  There are 3 or 4 pcbs that are VERY similar and will actually work for the audio , but fail to set the game into test mode due to a different pinout. 

Long story short..... crack open a manual and trace the wires... you may have to modify the pinouts to the audio pcb.
