Thanks John!

All credits should go to Andrew who opened the Pandora box that contained the Pico! Wink

With almost "real time" disassembler trace, it was really a piece of cake to understand how the Wand works when reading program barcodes, and just a bit harder to implement the drivers towards FI to "talk" to the HP41.

Extending the Pico to a Pico W would enable Wireless transmission of programs from a PC (if the Pico was to be powered by a LiPo).
Or simulating the cardreader (emulating the insertion of a card) could be used to send programs in the other way ...
There is also two FI flags that are not used by the system today, so with some clever MCode programming anything is doable, why not a "smart" USB-cable that provides file sharing capabilities with drag and drop to RAM and X-Memory...

Too much to do, with too little time ... Wink

Cheers,
Thomas
