Don't worry, I'd have trusted you if you just said 'it works'.

The the original PROMs you tested for me worked fine when I received them back, but one stopped working the next day. That's just my luck, which still hasn't changed. ( Today, the original bubble display I salvaged last week decided to lose a segment !. )

I didn't notice the new one was an 'A' version. Is there a significant difference ?.
