You're almost there! Your disk images are fine, but it sounds like there's a problem in the connections between the Mac floppy connectors and the CPLD, have you re-checked those? In particular, check PH0 through PH3, /WREQ, SEL, /ENABLE.EXT, and RD for opens or shorts between neighboring traces, for both connectors and the CPLD.
The Mini vMac "blank" images may have been read-only files, which is why you see the lock icon. Put the SD card in your PC, and clear the read-only flag for all the files.

Thanks for the suggestions. I'm still checking everything, but I found that PH2 and PH3 are shorted to GND. Is that right? It appears that the pins on the board are connected, for those, on the pads near the edge of the board, in Eagle.

Thanks!
