Pioneer series internal photo (17BII, 27S, 42S) Message #1 Posted by Lyuka on 16 Nov 2009, 3:56 p.m. Hi, there. Just now, I repaired my 42S which had dead '+' key by transplanting the membrane switch from broken 17BII. Some photo had been taken while repairing. Please take a look on HP-42S membrane switch transplantation and also HP Pioneer series calculator internals Regards, Lyuka

I had a trouble with a very bad 32SII 3 years ago and I went that way ( disassembling all the Keyboard ) I did it very careful... But after that the 32SII never worked OK again... Regards! Nacho

Re: Pioneer series internal photo (17BII, 27S, 42S) Message #5 Posted by geoff quickfall on 16 Nov 2009, 6:26 p.m., in response to message #3 by Lyuka I should have included that option! It is the one I use the most, sometimes adding a lump of donor plastic. I also filed my iron to a fine point with a convex shape to push the melted rivet up and out. Cheers, Geoff
