HP41 open source modules?

[rprosperi]

To possibly save you a lot of time, some comments to consider:

There are no sources for the connector, other than to scavenge one from another; unless you have a dead one to use, acquiring another one will cost you close to $50 at least.

Lots of people have made posts similar to this, but to date, I've not seen anyone ever announce successful completion. This doesn't man it can't be done, simply that no one has confirmed it can. It would seem if someone went to all the effort to do this, and succeeded, they would announce they had done so.

Though agreeably not inexpensive, the Clonix / Nov-64d modules are mature, robust, and have a thriving set of users and support here in the Forum.

"Expensive" is relative IMHO. If the goal is to learn to create something, it may be worth trying, however if the goal is to use an HP-41 with all the 500+ modules available, I'd reconsider Diego's modules.

Good luck either way.
