so the situation looks like this, I am currently using the vibra 16 isa in my 486/586 system. I am upgrading the AT psu to a ATX using a standard converter. However the vibra 16 uses -5v (there is a 5th pin on the back from the end)
So in my parts collection I found the opti which doesn't have the 5th pin so doesn't use the -5V rail therefore would be a simple swap and drop with the atx psu.
I don't know much about sound cards so I am hoping to get a general idea if these cards are far apart. I have a feeling the vibra 16 is a better card. If its not a great difference ill put the opti in and easy money.
However if the vibra 16 heavily outweighs the opti there is option number 3. Order a -5v convertor (CONVERT 20 PIN (NO -5V) TO 20 PIN WITH -5V & OPTIONAL ON/OFF SW)
Appreciate any feedback and advice
