Greene Hi; there are ten plastic rivets (heat molded) that maintain the top (four) and bottom edges (six) locked together. Also there are six "interlocks" (I have no idea if this is the correct term in English), three for each side of the calculator's "case". I have one HP48G in my hands right now and it's opened. I can scan both halves and you'll see how they are kept togheter. unfortunately this computer does not have the scanner and I have do digital camera. Wanna see the pictures? If so, let me know and I'll "scan" the calculator's image and post them here. Best regards. Luiz C. Vieira - Brazil

Re: Opening HP48GX Message #3 Posted by DF on 14 Mar 2003, 10:16 p.m., in response to message #1 by R.E. Greene I've posted an article in the article's forum, http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/articles.cgi?read=125 Adrian Drury has taken photos, added some of his own pointers, and written a detailed web page: http://www.contrib.andrew.cmu.edu/~drury/how2open.htm I've also seen postings advocating drilling out rivets from the front of the calc and replacing with countersunk black machine screws. Good luck, Dave
