The prevailing wisdom seems to be that the Mac 128K with 64K -A ROMs (342-0220-A and 342-0221-A) cannot be used with the 400K OA-D34V-22 floppy drive. For example:

However, once it's wrapped in its aluminium blanket it seems to be willing to play ball with the -A ROMs in my 128K, and System 2.0 appears to boot reliably.
