Hi Tony,

Time to order a full set since Katie’s recommendation is to narrow the board and then replace while testing each chip. I don’t have a replacement working board so,have to forgo the first step, unfortunately. Also I (1) don’t have a chip tester and (2) since the risky part is soldering and desoldering which has to be done whether or not I can determine that a specific chip is bad, I figure I’ll just plan on replacing them all, hope I don’t get any DOA chips or cause any infant mortality, and only resort to buying a tester if brute force fails. I did buy a nice desoldering gun primarily for this project, which helps.

I wanted to make sure I decided your handwriting, though. Are all the chips on the third sheet (page 2) 4014, or are some 4016? No insult intended; I have PhD handwriting, which is worse.
