Any comments to add???
Just playing around, I really like the price point of the Pico, especially now that it has wifi. I'm also interested in trying the PIO programming at some point, but it's not needed for the first project.
The board itself is just an interface to the QL ROM bus, could be used for anything that doesn't require the extra signals available on the side expansion, so no RAM expansion for example, but in theory it could run tcp/ip (no plans to do that myself, though), perhaps math acceleration, sound, MIDI, external keyboard, bluetooth devices, etc.

The first project I will attempt will be a wifi microdrive.
I've read about the OqtaDrive and it seems it already does wifi among so many other things, but it requires pairing it with a Pi Zero and can only work as MDV 3+ unless you use it to replace the internal microdrive. I assume it's also relatively slow as it goes through the ZX8302.
If that can be made to work, my next project could be a wifi ROM chooser. It would require very tight timing, though, and the Pico to start before the 68008, so not sure whether it's possible.

Twice as wide would be better, also for the ground traces.
If you then keep the traces between decoupling capacitors an IC power pins short and wide, you should be okay even without ground plane.

The Pico boots minimal code in almost 200 msec after power-on, which is less than the reset times I have seen on my QLs.
How reliable that would be, is a different question.

Good to know as I have not measured the QL reset time, yet.
From some experiments with the Pico dev board and other projects I see around, I think feeding ROM data to the QL should be attainable.

Tried it with PhysicalDevice0 / PhysicalDevice1 / PhysicalDeviceA and  PhysicalDevicea in the *.ini. Doesn't work. DIR A: in PowerShell (with a DOS Disk inserted) is working.

Oops: Just detected, FLP1_ now does no more work with QPC2. It seems I have a serious problem :‑(

Unfortunately the drive path is specific to your machine. And I am not a windows user so i cannot actually help you find it, your on your own there!

Ah, thank you, that was the solution.
