I actually talked to Mike over at Sytek - he said the only access to that module is from the bottom of the console, which would require tipping it up on end or on the rear, removing the legs and then removing the bottom panel. Sounds like I'd have plenty of access once I did that, but it's going to be pretty disruptive. Seems like there is some debate over the best way to access, either through the rear or bottom. If I can actually get in there enough to at least clean the switches, and possibly replace the socketed IC through the rear without having to tip the thing up on end, that would be preferable. I'll at least be able to take a closer look this evening. Thanks so far for the suggestions. Bill
