HP41 with Pico RP2040 attached, update - MeindertKuipers - 03-27-2024 02:20 PM
Hi all,
I have posted an update earlier, announcing that I have been succesfull to implement emulation of the HP-IL module and the PILBox in my Pico-RP2040 breadboard setup. This means that there now is a direct connection via USB to the pyILPER virtual HP-IL devices on a host PC, and the host thinks that a PILBox is connected. The YouTube video below is proof of this:
Next step in the project is to make s suitable PCB, one version for development using a Pico module, and the final product version in the shape of a long module. Besides that the user interface is needs to be improved to make it really useful. In addition there in a microSD card on my breadboard and I want to make this accessible as an HP-IL mass storage device.

All public information on my HP41 projects is now on my github at https://github.com/mjakuipers. This includes all sources for the MLDL2000.
An older version my the Pico/RP2040 project is available there, any updates will be done when the time is right. No plans to do an HP71 sniffer or peripheral. Just pickup the public sources from Andrew, Thomas or myself and take that as a starting point for something nice.
For announcements and updates this forum will be the place to watch.

Excellent job, Meindert!
Gotta have one, when finished.
