Dave,
I THINK it has a rounded edge. As I said, I know less than nothing about these. Did you get the email I sent? Only because you're a nice bunny, I'll part with the Z chip for you. Do you need the W or any of the others?

Remember sending me the plastic Sahara Tahoe box a few years ago? Among other things it contained a hanger for "dainties"... ! We'll work something out that won't cost you your kid or your house . Maybe a cool Nevada trinket or two...

Are the "pink" chips really pink (like pepto-bismol) or are they more salmon-y or coral-ish? The I and O are kinda salmon/coral, and the W seems to be about the same color, but a little chalky looking.

I don't think our email is working , and in a couple of hours we've got "stuff" starting up that will have me off-line more than online until Sunday night . Entertaining, grandkids spending the night, etc.
