Is it possible to boot the original Macintosh, or
perhaps the Mac 512K or
Mac Plus, from the external floppy drive?
Yes.
I seem to recall doing that on a regular basis with the 128k, and
although I don't recall having ever booted from an external floppy with
the Mac Plus, I have booted the Plus from the old Hard Disk 20 that used
the floppy interface. So I would imagine that an external floppy drive
would also be bootable on that machine.
In fact, I thought (but could be wrong) that you could boot all Macs that
had a floppy port via an external floppy disk.

Cool. So can I assume that if there is no disk in the internal drive, but
an external drive with bootable disk is attached, the Mac will find that
and boot from there?

Yup, the Mac will search all available floppy drives for a bootable
disk, and as long as the disk and drive are good, it will boot from any
attached floppy drive. IIRC, it starts with the internal drives, then
the external drives, so if you put a system disk in both drives, it
_should_ boot the internal one. It also generally does the same thing
with SCSI devices (Plus and up), although IIRC it searches by the ID
number, and won't differentiate between internal and external.
