Request: HP-41C/CV/CX logic boards to support reverse engineerin

[brouhaha]

I previously requested 12C calculators for reverse engineering to improve the accuracy of Nonpareil, and thanks to the generosity of folks here (especially Mark), I have been able to start that work. I think it would also help if I could get one or more spare 41C/CV/CX logic boards. I don't want anyone to sacrifice working calculators for this, but if anyone has a spare board (perhaps as a result of installing Monte's 41CL upgrade board) which they're willing to sell, please let me know.

The plan is to build a custom Nut PC board for reverse-engineering purposes, physically much larger than the 41 board, but containing most of the components from it, along with additional sockets and connectors for convenient logic analyzer and oscilloscope probing, and connecting custom interface hardware.

Thanks!
Eric
