These primitives are required by the kernel:

\ Definitions:          dodoes exit
\ Control flow:         0branch
\ Literals:             (literal)
\ Memory access:        ! @ c! c@
\ Aritmetic/logic:      + nand
\ Return stack:         >r r>
\ I/O:                  emit open-file read-file close-file

I suppose this could be squeezed a bit by excluding C! and C@.  Also,
I managed to define 0BRANCH and (LITERAL) in terms of other
primitives, but the system became unbearably slow.

Thanks, a PDF would be nice.

Running Hayes' CORE tests results in 77 failures (out of how many
tests? I don't know).  I believe many of those are due to a stubbed
UM/MOD.
