Do you have an idea when this might happen?

Would be happy to. I'm planning on tidying up the Microdrive code (running on the 2nd core) and releasing standalone so people can mess with it. It is all about timing and luckily the Pico comes with some nice routines. That is great. Thank you very much! Note I used the C SDK and not Micropython. ...

Kind regards

The problem is that it's limited by GPIOs. It has 26, but with 16 needed for the address bus and 8 for the data bus, plus the control bus needs a few, the microdrive hardware needs another 7, 4 for the RS232, one more for the network... Either 2 Picos working in tandem, or significant GPIO expansio...
