Microemacs in all its flavors (3.8x, micrognu, v30, etc) keeps text memory
resident.  It would be next to impossible to have this work on CP/M-80 in
any reasonable way, since you don't have any memory to play with.

There was a rumoured version that did some paging, but I have not seen it,
nor do I know where it exists.

Other free options would be SCAME or JOVE.  All are all relatively
feature-laden (read: large) for CP/M, and none to my knowledge pages
anything to disk.

I suggest you try to get a MINCE (from Mark of the Unicorn) or a Perfect
Writer 1.x (a repackaged MINCE).  I don't think either is being sold
anymore, but who knows what you might find at a swap meet somewhere.
Mince came with source for the command set, and object for the redisplay
and buffer manager so you can add features.  Doing so requires the BDS C
compiler.  Perfect Writer was a binary only distribution.  Both would edit 
large files by paging things out to disk.

The PW manual is a particularly nice intro to the basic functions of the
emacs family.
