I was beginning to suspect as much as my attempts got nowhere. My board has two empty spots with holes filled with solder. That is not really a problem as I have a professional solder sucker. :-) I assume these might have to do with addressing. Then there are four that I suspect are the memory chips and they are surface mount. Not so sure I want to delve into that as my eyes aren't what they used to be. I guess the first step would be to see if the chips are even available. bill
