hp48sx RevA Message #1 Posted by andy on 30 July 2002, 9:53 a.m. My hp48sx has the rev. A rom (which as quite a few known bugs). How does this affect its value (I also have the original manuals, the quick reference book, the hp eqn. library card, and the serial cable). Andy

A NIB 48SX might reach 100$ I don't know. Seems like most mint are in the 50-80$ range, more if apps card packs are included of course.

Re: hp48sx RevA Message #3 Posted by Jeffrey_G on 30 July 2002, 12:37 p.m., in response to message #1 by andy I have a 48SX. How can I tell the ROM release?

Re: hp48sx RevA Message #4 Posted by andy on 30 July 2002, 12:48 p.m., in response to message #3 by Jeffrey_G To determine the ROM release of your 48sx do the following: 1.) press and hold the "ON" button 2.) press the "D" button then release both buttons 3.) your screen will go blank and have 3 vertical lines evenly spaced across. 4.) press the "backspace" key 5.) press the "eval" key and your ROM release will be displayed 6.) press "on"-"C" to exit If you do everything properly you won't loose any of your files either.
