as the title states, can i even split the nvram loaded with 12p (tuned) down to fit onto a 27c128? or have i gone an done a silly thing by tuning with 12p? i dont have access to a 27c256 or larger, its for a '808' v8

Not as far as I know. It needs a 27C256. I just cut them off and solder in a 27C512 and use 8000 offset.

I doubt it. they are often too slow to work and one time program only what you can get off the shelf and generally the ones you need only found as clones of obsolete 27c series proms
