No, mop isn't just a replacement for tftp. mop is the "maintenance
operations protocol". Much more specialized than tftp.
Some DECstations can select to boot through tftp or mop, yes. VAXen can
only boot through mop, no tftp stuff in there. All DEC equipment that can
netboot knows about mop. Very little know about tftp. In fact, I think the
DECstations are the only ones I know of. MOP exists for terminal servers,
PDP-11s, VAXen, and probably a bunch of other stuff. MOP can be used for a
lot more than just donwloading an image that you want to run, but all
other uses are more or less forgotten today, I think.
