TF536 to 68000 switch

odd question.
As the CD A570 will not boot with the TF536. Is it possible to put a 68000 in there as well (on a custom PCB - to have 68000 & TF board) and switch between the 2, by switching gnd and power between the CPUS ?

It takes a bit more than GND and VCC. There's a switcher called "garlic" that will do what you need, posted
here.
Edit: Although now that I reread your post, it sounds like maybe you're wanting to switch CPUs on-the-fly, i.e. after booting the 68000? That is not possible.

Hi,
Have you considered patching the A570 extended ROM so it works with the TF536 ?, see..

This is definitely a software issue and not a hardware issue. Try the alpha version (98-114-a570) of Extended ROM v2.35 for A570 and it should solve your issues.
The A570 version is AFAIK only available on the Discord channel.
