Meshtastic 64 – A meshtastic radio for the Commodore 64

It pains me to mention this but I don't think it's responsible not to: https://github.com/meshtastic/firmware/issues/4030

At time of writing (2025-09-27, plus or minus a timezone), there does not appear to be any serious attempt to secure application-layer message contents. (At least, not yet)

My hope is that this cool new radio link option will still gain traction and grow and develop without painting itself into a corner, security-wise.

To wit- security hints on https://en.wikipedia.org/wiki/OSI_model have improved substantially since my last readthrough.

I appreciate you pointing that out. I've been curious about meshastatic and wondered how well the encryption was being handled.

MeshCore seems to enforce a strict separation between client devices and repeater devices, which is a significant downside for many use cases.
