    SE/30 - some rows on the CRT are offset a little bit

    SE/30 - some rows on the CRT are offset a little bit

    Thank you -- where were you yesterday? :-) But yeah... the silly thing is I *know* this, but hadn't worked with this particular type of package before, and was just over-thinking it. I thought maybe they were going for simulating the "crimped" end with the black strip, although I see now the...
