While I'm not worthy to even polish Allan's shoes when it comes to chips this is an interesting question. In Chip Rack #6 the chip is listed two ways: if used probably genuine and, if new, probably Borland. Then in #7 the genuine listing was removed implying that all are suspect. So two questions: why was the change made in TCR #7; and would this be the first Borland chip to be found in used condition? The chip in my collection is very worn.
