Flex for 41C
Please,

Does anyone have the dimensions of flex-pcb used in HP-41 for connecting batteries and modules to main board?
I know Diego has a replacement for selling, but they are expensive to me and I'll still have to import them, which may inccur in taxes. So, I'll try some pcb industry by here in Brazil.

I got one flex in a forgothen 41C, but it is so destroyed. I couldn't take the measures on it.

I reopenned an old discussion and solutions about this, but my post got the last position and I'm afraid no one would see my needs.

Best wishes,
Artur

RE: Flex for 41C
Seems unlikely that it would be cheaper to have one made but if I was going to try to replicate it I would download an image from one of the auctions, import it into autocad and scale the image to actual size. From there you could trace out the circuit design and have a reasonably accurate template.
