Yup.   You kind of need an RRD40 or RRD42, unfortunately.   You may be
able to jumper a non-DEC drive to run with 512-byte blocks (actually,
I'm not sure whether it's 512-byte blocks you need or 2048 - it's not
the default, whatever that is).

The non-MAXine floppies are all SCSI-based, so they should be
bootable.  I don't think the MAXine will even boot off its floppy.
You could dd the first N blocks of the CD-ROM onto a hard drive with
some other machine to make yourself a root partition and then and boot
off of the hard drive.  Indeed, it might be winning to partition the
CD-ROM with this in mind.
