Thanks for the URL. It provided me with some hope, but my fault appears to be different. Before I go about "fixing" it I'd like to be sure it's broken :-)
My very early C differs from the one in the article in that
1) it seems to be made out of gold :-)
2) the processor board is held down with what look like gold nuts on the bottom posts.
3) The connectors between the display and the keyboard PCB appear to be in a poor way...
With the calculator face down and the display closest to me, there are three sets of connectors.
the first has 6 connections, the next 7, and the last 5 or 6??
The furthest right of the right most set is missing. From the look ogf the board under a loupe, there may have been a link here at one stage. The images on the page I was referred to are a little difficult to make out, but it appears that the connectors on the CV pictured may be a little different????
Two of the other connections have lifted from the board, but are still connected to the tracks (which have also slightly lifted
One further connection has lifted from the pad.
All of the connections on the keyboard PCB appear to be OK, except for the missing link.
I am planning to resolder the link that has lifted from the display board, and replace the missing link. The tracks that have lifted can stay as they are.
Before I attempt this:
Is the last link really missing, or was this link not installed?
Has anyone done a repair like this, and if so, do you have any advice.
Oh, and the posts appear to be in great condition, although the screws at the top were quite slack (i.e. I could tighten them almost half a turn before meeting resistance (this tightened up the case nicely, but failed to fix the problem)
