Schematic for HP-41 keyboard?



#4

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!


#5

Schematic is in the 41C service manual.

Page 35 in \INTERN\HP41SRVC.PDF on the Museum CD 5.

#6

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!
