Not on my part, certainly! Anyone else?

Dave mentioned flex board2board connections for metal-backed 71's and zebra strips for plastic-backed 71's. Flex pressed against gold plated contacts was used to connect the port module assembly shell to the 41C main board and zebra strips to do the same for the CPU board. As mentioned, flex has been used as a substitute when zebra strips were unobtainable. Although not interchangeable, flex and zebra strips perform similar b2b functions.

Knowing now that there is a suitable source of custom zebra strips at hobbyist volume is great news for all those seemingly unrepairable calculators.
