Paul, should you decide to move on to other things, consider letting me have that unit to help repair mine.? I don't think mine has much wrong with it but it's practically dead.? It worked and then one day didn't.

Hello to the group.
Its not apparent that it was a lightning strike but 12 ICs is a lot of ICs. Will bet there are several more hiding. But each replacement truly fixed an issue. The unit was given to me and am not sure now the fellow likes me or hates me??? It was sort of a doorstop and home for mice. One of the dirtiest pieces of gear I have run into. But the inboard and and analog were as clean as new because the mice couldn't get there.
No matter dropped the out board logic and thoroughly?removed the stuff (Nice wording) Now the board is very clean. The mice didn't really nibble anything. Someone took the fan so that was the entryway. They nibbled a bit on a couple of wires easily repaired.
But I would love to get some parts to play with. Outboard logic, cpu board just something to point me in the right direction at this point. Its possible at this stage I have a inboard issue. But I doubt that because if that is the case the front panel tests would run.
Or decide to send it to the basement for a years punishment for not showing me how to fix it. Chuckle.
Good to know others have the same challenge. These are old so maybe thats the way it is.
I have had to replace eproms the the 3456a due to age.
