If I find a safe way to remove the marker ink [...] If you mean by 'label' the printing directly on the black plastic chip case, I've had some success with a Q-Tip dabbed in denatured alcohol. Yes, you need to be careful-- normal coatings on PC boards wouldn't like an alcohol bath (that's why I use a Q-Tip)-- but it should work. If you mean a printed paper label, I don't know what to tell you. Also, you might want to wait a day or two to give anybody a chance to tell me that this is a dumb idea-- I'm not a tech. or anything like that :-) St. Olaf College has very little to | M M | M M M | M M | M M M | M M | do with the things I talk about! | M M | M M M | M M | M M M | M M | | M M | M M M | M M | M M M | M M | Dave Brown: brownd@thor.acc.stolaf.edu | | | | | | | | | | | | | | | | | | "I _like_ programming the DX-7!" |_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
