Hi, I have some trouble with my mbfm. I’m building a minimal setup with
only core module and fm module. The problem is that it is completely
silent. I have some ideas of what it might be, but before I start describing
every detail I wonder if anyone has any experience with broken OPL3:s.
Are there any typical symptoms or are they just dead?
I wonder this because of the history of my chip(s). I salvaged some soundcards
from the junkyard a couple of years ago (I must be psychic because I didn’t know
about this project and I always wondered why I saved ISA-cards ;)) , although I
took them out of a computer they have most likely been exposed to a lot of moist
(but hopefully not rain). I might add that they empty the used electronic bin quite
often, so it is not likely that the computers had been there for more than a week
or two. After that they have been stored in my “playingroom” in boxes and only
touched when I was looking for some card (have helped quite a lot of people with
my stock :)). Finally I only had an unregulated soldering iron with a max temperature
of 450 C when i desoldered them. I was quick and and they were not even warm
on the outside immediately after I was finished, but you never know about the
inside.
I have one spare OPL3, but before I switch I want to be sure there’s no other
problem.
