HP-41CL New Serial connection and port recovery.

[PeterP]

Diego, this is not just a very interesting but potentially very useful design exercise. You might have been following the amazing work others like Meindert etc have been doing here with the Pico RP2040 (see e.g. here).

For that a "module type" connection is needed and one could use one of the 3D printed module shells available.

Meindert et al might be very interested in your design as the original "module fingers" are not that easily replicated. But your design or some small adjustment of it could be used potentially.

Where did you source the spring loaded contacts?
