Re: HP41 Brain Transplant (CV vs CX) Message #2 Posted by Vieira, Luiz C. (Brazil) on 19 May 2003, 12:29 p.m., in response to message #1 by Michael Fink
Hello, Michael;
if both 41's are fullnut, the LCD assy is exactly the same for both of them. The CX's mainboard should work fine in any C/CV keyboard/LCD, provided they are fullnuts, of course.
You should take special care with both:
1- the zebra connectors between the mainboard and the keyboard 2 - the pressure over them;
in the second case, using plastic washers will help if you build the CX's mainboard in the C/CV case and have problems switching the "franken"calc on. I do not know the thichness, but others in here will surely post the measure. The washers are required only if after rebuilding it, the calcualtor does not switch to on or freezes/shoot off by its own.
Oh, yes; if you can, keep the original CX's back plane. The CX's back label shows active ED's keys instead of regular ALPHA keyboard, shown in the C/CV's back label.
Success!
