Re: Opening HP41C Message #3 Posted by John Robinson on 8 Jan 2010, 3:12 a.m., in response to message #2 by Vieira, Luiz C. (Brazil)
I have successfully disassembled the 41 keyboard by "popping" off the top of the heatstakes with a small screw driver. The plastic that comes off is kinda donut shaped. By doing this instead of shearing off the whole top of the heatstake with a knife, the centre of the heatstake remains. To reassemble, I use "hot" glue, while maintaining pressure on the keyboard from behind.
I actually squish down the glue with my finger (after licking it first) to set the glue quicker and force a little more around the heatstake.
I have done this on five or six 41 calcs now and it works a treat !!
Cheers,
John
