Title: Vintage Audiomedia nubus card question/help needed Post by: FunkySqueek on September 04, 2011, 08:48:05 AM I have aquired an Audiomedia I (rev B.1) Nubus soundcard for vintage Mac. When I put it into my Mac IIfx the computer starts up and when it comes to read the cards it halts with "buss error" - when I remove the audiomedia card, the computer works as normal.
There seems to be something with the Audiomedia card that causes the computer to throw a wobbly when it reads the card's identity. Does anyone know if I need to set the card's jumpers in a particular way? There are 3 jumpers, 2 near the main CPU chip look likely. Just for fun, if I remove the card's erprom or cpu chip the computer boots just fine - but of course the Audiomedia is not seen. Booting with extensions off makes no difference. Clues anyone?

wrong nubus slot try to zap the pram use the correct os run the os in 16bit mode if it's os7 or later the IIfx was an oddball, perhaps try something like a IIci or quadra |
