Broken chip Message #1 Posted by Gonzalo Fernandez (Spain) on 2 Oct 2006, 2:56 p.m. I have an HP41CV with a broken 14 pin DIP chip (1826-0566D RAYC, Power supply bipolar) Where can I find a replacement? thanks

Re: Broken chip Message #2 Posted by Eric Smith on 2 Oct 2006, 4:12 p.m., in response to message #1 by Gonzalo Fernandez (Spain) Generally only from another HP-41C or HP-41CV.

Re: Broken chip Message #3 Posted by Randy on 2 Oct 2006, 4:24 p.m., in response to message #2 by Eric Smith Yes, only from another 41. Later units have 1826-0953-1 IC's. They can be used in older units by removing R2 (100k) and R3 (1M).

Re: Broken chip Message #4 Posted by Gonzalo Fernandez (Spain) on 3 Oct 2006, 2:36 p.m., in response to message #3 by Randy Do you have a spare 1826-0566D chip? I can exchange by RAM or ROM HP41 chips if interested.
