Here are pictures of weirdest repair job i had…
I had not working FDD midi drive, after opening i found EPROM not properly fitted inside socket…
They are hard to pull out and enclosure was sealed so nobody tampered it…
I can’t imagine how much “G Force” should be apply to lift that ic from socked… of course enclosure don’t show any sights of shock / drop.
After pressing it down, everything start working correctly…
