Hey everyone, I'm new to Apple, as I picked one up locally with the green monitor w/tilt screen, duodrive, 64k/80 column card. It worked, but had problems, wouldn't pass diag. I did some poking, and found the small chip just to the left of the ram had a broken lead, and I suspect it had some bad ram chips. Re-seating didn't help. It was a MB manufactured in 1982, and when booted, showed 'Apple ]['. I found a 1984 MB on ebay, tested, passing diags, for $20, so I bought it. I changed the MB, and it works great. Now, when I power it up, it shows 'Apple ][e', instead of just 'Apple ]['.
