Hi, I recently received an HP 9815A ... working, except that the display is dead. (I.e., I can enter numbers, do calculations, and print the results on the integral printer.) Does anyone have experience with this machine? The display (about 5 or 6" wide, 1" tall) is a Burroughs Panaplex II, with the following markings: Kr 85 BR 16252 An odd little pointed glass cone juts out of the back of the panel, in the center. thanks, Stan Stan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html www.allegro.com/sieler
