dead modem?

[psypher]

I looked into your Mac model.  I can see that it has a SMT version of the 85C30.    That makes replacing it a nightmare.  However, I did read that this motherboard does odd things (like no serial or AppleTalk) when there are bad caps.  Do you have AppleTalk setup?  That would be another way to verify the SCC is working or not.

Here is some info on the re-capping your Mac:

I dont have AppleTalk set up but i just ran the snooper test and it didnt pass for modem or printer it said no hand shake and when it went though the baud rates it also cam back bad. what chip is it i have another parts board that maybe i will be able to get what i need from it. I also did a recap about two months ago so that shouldnt be an issue.

update I think its a AM85c80 which does the scsi and scc is it possible that only the scc would have failed? scsi stuff is still fine?
