TF536/68000 switching

No the altram and IDE only respond to the 030 lines.

Gotcha. Thanks. I will plan on using the Lightning IDE then.

I do recall 2018 @Matze aka Matthias Heinrichs already created a PCB called "Garlic" where two CPUs are placed, saw recently a post on A1k.org where one user used 68000 and TF536 on it and it worked 🤔

Oh very cool. Thanks very much for that. Guess I have to install Eagle now. :lol:

I'm still going to need to customise, to try to fit things into the Stacy, but this will be a great help.

Excellent. Got garlic converted over to KiCad format, where I am more comfortable browsing. This looks like a very workable solution. The GAL option looks fine, too, but I figure I'll work with the setup that's known to work with the TF536. Thanks much, @8 Bit Dreams!

One thing I notice when looking at the garlic PCB is how wide the traces are. 0.4064 mm. When designing my own relocator board, I've been using 0.250 for everything except VCC, which I made 0.3 just for good measure. Since I don't know a whole lot about board design, I wonder if anyone has any comment on that. I'm not having to relocate a tremendous distance (the longest traces are around 7 cm), and I've just been working under the assumption that the default size in KiCad is fine for this kind of purpose.
