Has there been a board revision, or is the 4MB still a hack?

Still a hack. But a professional one :)

You wanted to add a real physical floppy drive to a MiniMig? For reading Amiga formatted disks using a standard PC floppy disk drive?

The actual drive is standard, no!?
The drives are not standard.

But the variations are probably controller dependant.

Amiga floppy drives spin at half the rate of a PC floppy drive when a HD disk is inserted because Paula cannot accept the data above DD rate.

There is something about the _DC & _RDY lines (missing on most PC drives) and DS0 & DS1 being swapped too.

What CPU is it, just a plain 68000? And chipset still ECS?
Yes and Yes. You can overclock the 68000 to 56 MHz from what I've read.

Isn't Chameleon 64 with the latest Minimig core a better option like the Minimig 4MB with arm controller?

I'm not 100% familiar with the support for the Chameleon64 but hardware wise it is much better than a MiniMig v1.1 PCB.
