Schematic for HP-41 keyboard? Message #1 Posted by Paul Brogger on 12 Apr 2003, 2:41 p.m. I'm having trouble with an HP-41CV, and I think it's in the keyboard. I'm wondering whether anyone has a schematic available so I can try to correlate behavior with electrical design, and perhaps get some hints as to where I should look. Anybody got one? A link? (If it's something that may be e-mailed, please take the "NoHormel" out of my address above, and send it my way.) Thanks!

Re: Schematic for HP-41 keyboard? Message #3 Posted by Ellis Easley on 12 Apr 2003, 3:52 p.m., in response to message #1 by Paul Brogger There is an HP41C service manual on the MOHPC CD-ROMs: cd5\intern\hp41srvc.pdf The schematic is on page 36/45. I also have a 57KB .pdf file which is a schematic of the HP41C. It's not an HP drawing, it doesn't have a name on it. I'm sure I downloaded it from a site that was mentioned here but I can't remember where the site is. I'd be happy to send you the file - in fact I just did!
